Introduction to Data Types in C - Quiz

What is the output of this code? 

#include <stdio.h>
int main()
 {
  int a[5] = {1, 2, 3, 4, 5};
  int i;
    for (i = 0; i < 5; i++)
          if ((char)a[i] == '5')
             printf("%d\n", a[i]);
          else
             printf("ATNYLA\n");
 }

  • AProgram will compile and print the output ATNYLA
  • B Program will compile and print ATNYLA for 5 times
  • C Program will compile and print the ASCII value of ATNYLA
  • DThe compiler will flag an error

What is the output of this C code? 

#include <stdio.h>
int main()
 {
  signed char chr;
  chr = 200;
  printf("%d\n", chr);
  return 0;
 }

  • A-56
  • B200
  • C-200
  • DDepends on the computer

What is the output of this C code? 

#include <stdio.h>
int main()
 {
  float f1 = 0.1;
  if (f1 == 0.1f)
  printf("equal\n");
  else
  printf("not equal\n");
 }

  • Anot equal
  • Bequal
  • COutput depends on compiler
  • D None of the mentioned

Which is correct with respect to the size of the datatypes?

  • Achar > int > float
  • Bint > char > float
  • Cchar < int < double
  • Ddouble > char > int

What is the output of the following C code on a 64 bit machine? 

#include <stdio.h>
union Sti
 {
  int nu;
  char m;
 };
  int main()
   {
    union Sti s;
    printf("%d", sizeof(s));
    return 0;
   }

Which of the following is not modifier of data type in c?

  • Aextern
  • Binterrupt
  • Chuge
  • DAll

Suppose a C program has floating constant 2.76, what's the best way to convert this as "float" data type?

  • A(float)2.76
  • B2.76f or 2.76F
  • C2.76 itself of "float" data type i.e. nothing else required.
  • Dfloat(2.76)

What will be output when you will execute following c code? 

#include<stdio.h>
int main(){
    volatile int x=34;
    printf("%d",x);
    return 0;
}

  • A34
  • BGarbage
  • CCompilation error
  • DWe cannot predict

What is the output of this program? 

#include <stdio.h>
int main()
{
    if (sizeof(int) > -1)
        printf("Yes");
    else
        printf("No");
    return 0;
}

  • ANo
  • BYes
  • CCompile time error
  • DRun time Error
 What would be the output of the following program?


#include<stdio.h> 
 int x = 40 ;
void main()
{

    int x = 20 ;
    printf("\n%d ",x);
}
