If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.
Q 1 - What is the output of the below code snippet?
#include<stdio.h>
main()
{
int a = 1;
float b = 1.3;
double c;
c = a + b;
printf("%.2lf", c);
}
Answer : A
Explanation
2.30, addition is valid and after decimal with is specified for 2 places.
Q 2 - What is the output of the following program?
#include<stdio.h>
main()
{
printf("\");
}
Answer : D
Explanation
Compile error, Format string of printf is not terminated.
Q 3 - Compiler generates ___ file.
Answer : B
Explanation
(b). Compilation is the process of translating high level language statements into equivalent machine code, which is object code.
Q 4 - What is the output of the following program?
#include<stdio.h>
int* f()
{
int x = 5;
return &x;
}
main()
{
printf("%d", *f());
}
Answer : D
Explanation
It is invalid to return local variable address as the local variable gets removed after the functions execution is completed.
Q 5 - Which of the following functions disconnects the stream from the file pointer.
Answer : B
Explanation
fclose(), it flushes the buffers associated with the stream and disconnects the stream with the file.
Q 6 - In C, what are the various types of real data type (floating point data type)?
Answer : C
Explanation
There are three types of floating point data type = 1) float with storage size 4 byte, 2) double with storage size 8 byte, and 3) long double with storage size 10 byte.
Answer : A
Explanation
The bitwise AND operator & compares each bit of the first operand with the corresponding bit of the second operand. During comparison, if both operands bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.
Q 8 - Which of the following statement can be used to free the allocated memory?
Answer : B
Explanation
The library functionfree()deallocates the memory allocated by calloc(), malloc(), or realloc().
Q 9 - During preprocessing, the code#include<stdio.h>gets replaced by the contents of the filestdio.h.
B - During linking the code#include<stdio.h>replaces by stdio.h
C - During execution the code#include<stdio.h>replaces by stdio.h
D - During editing the code#include<stdio.h>replaces by stdio.h
Answer : A
Explanation
Preprocessing enlarges and boosts the C programming language by replacing preprocessing directive #include<stdio.h>with the content of the file stdio.h.
Q 10 - In the given below statement, what does the pf indicate?
int (*pf)();
Answer : A
Explanation
pf is a pointer as well holds some functions reference.
