C output questions and answers pdf download

The strcat function. It takes two parameters, the source string and the string value to be appended to the source string. Do these two program statements perform the same output? Yes, they both do the exact same thing, Explain Which is to accept the next key pressed by the user and assign it to variable named letter. Text files contain data that can easily be understood by humans.

It includes letters, numbers and other characters. On the other hand, binary files contain 1s and 0s that only computers can interpret. Yes, it is possible to create a customized header file. Just include in it the function prototypes that you want to use in your program, and use the include directive followed by the name of your header file.

Dynamic data structure provides a means for storing data more efficiently into memory. Using dynamic memory allocation, your program will access memory spaces as needed.

This is in contrast to static data structure, wherein the programmer has to indicate a fix number of memory space to be used in the program. Explain How would you place this character as part of the output on the screen? For example, you can write printf?

Storing data on the heap is slower than it would take when using the stack. Explain However, the main advantage of using the heap is its flexibility. Slowness in the heap can be compensated if an algorithm was well designed and implemented. Preprocessor directives are placed at the beginning of every C program. This is where library files are specified, Explain Which would depend on Explain What functions are to be used in the program. Another use of preprocessor directives is the declaration of constants.

Preprocessor directives begin with the symbol. What will be the outcome of the following conditional statement if the value of variable s is 10?

Just the same, s! Order of precedence determines Explain Which operation must first take place in an operation statement or conditional statement. On the top most level of precedence are the unary operators! This is because C language is rich in features that make it behave like a high level language while at the same time can interact with hardware using low level methods.

The use of a well structured approach to programming, coupled with English-like words used in functions, makes it act as a high level language. On the other hand, C can directly access memory structures similar to assembly language routines. In C programming, there is a data structure known as queue. A queue represents a line wherein the first data that was stored will be the first one that is accessible as well. In the first expression, the increment would happen first on variable a, and the resulting value will be the one to be used.

This is also known as a prefix increment. In the second expression, the current value of variable a would the one to be used in an operation, before the value of a itself is incremented.

This is also known as postfix increment. C language is a case sensitive language. An endless loop can mean two things. One is that it was designed to loop continuously until the condition within the loop is met, after Explain Which a break function would cause the program to step out of the loop. Another idea of an endless loop is when an incorrect loop condition was written, causing the loop to run erroneously forever.

Endless loops are oftentimes referred to as infinite loops. What is a program flowchart and Explain How does it help in writing a program? A flowchart provides a visual representation of the step by step procedure towards solving a given problem. Flowcharts are made of symbols, with each symbol in the form of different shapes. The word void is a reserved word in C language. Assuming that INT is a variable of type float, this statement is valid.

When you create and use functions that need to perform an action on some given values, you need to pass these given values to that function. The values that are being passed into the called function are referred to as actual arguments. A newline escape sequence is represented by the n character.

More spaces can be added by inserting more n characters. For example, nn would insert two spaces. These are errors that occur while the program is being executed. One common instance wherein run-time errors can happen is when you are trying to divide a number by zero.

When run-time errors occur, program execution will pause, sExplain Howing Explain Which program line caused the error. In using functions in a C program, formal parameters contain the values that were passed by the calling function. The values are substituted in these formal parameters and used in Explain Whatever operations as indicated within the main body of the called function.

Control structures take charge at Explain Which instructions are to be performed in a program. This means that program flow may not necessarily move from one statement to the next one, but rather some alternative portions may need to be pass into or bypassed from, depending on the outcome of the conditional statements.

The switch statement is best used when dealing with selections based on a single variable or expression. Explain However, switch statements can only evaluate integer and character data types. Global variables are variables that can be accessed and manipulated anywhere in the program. To make a variable global, place the variable declaration on the upper portion of the program, just after the preprocessor directives section. Enumerated types allow the programmer to use more meaningful words as values to a variable.

Each item in the enumerated type variable is actually associated with a numeric code. Yes, that is allowed in C programming. To summarize our programming questions list does not contain only answers In addition to, it also contains all the aspect of the problem, if any programming questions have multiple solutions then we try to add all possible solution of the problem actually programming problem.

We also divide all the c programming questions to multiple levels. B Equal. C Greater than. D None of above. So double constant 5. Number likes 4. So the answer is A Share this question with your friends. B to C to D to Which of the following is definitely the input? Correct option is: D. Latest Government Jobs Which of the following step will be the last? Directions : Study the given information and answer the questions:. When a number arrangement machine is given an input line of numbers, it arranges them following a particular rule The following is an illustration of an input and its rearrangement.

Correc t option is: B. Which element is 2nd to the right of the one which is 4th to the left element in step I?
