Determine Output:

void main()
{
      char *p;
      p="%d\n";
      p++;
      p++;
      printf(p-2, 300);
}

Determine Output:

void main()
{
      int c[] = {2.8,3.4,4,6.7,5};
      int j, *p=c, *q=c;
      for(j=0;j<5;j++){
            printf(" %d ", *c);
            ++q;
      }
      for(j=0;j<5;j++){
            printf(" %d ", *p);
            ++p;
      }
}

Determine Output:

void main()
{
      int a[] = {10,20,30,40,50}, j, *p;
      for(j=0; j<5; j++){
            printf("%d" ,*a);
            a++;
      }
      p = a;
      for(j=0; j<5; j++){
            printf("%d" ,*p); 
            p++;
      }
}

Determine Output:

#include<stdio.h>
void main()
{
      char s[]={'a','b','c','n','c','\0'}; 
      char *p, *str, *str1; 
      p=&s[3]; 
      str=p;
      str1=s;
      printf("%c", ++*p + ++*str1-32);
}

Determine Output:

void main()
{
      static char *s[] = {"black", "white", "yellow", "violet"};
      char **ptr[] = {s+3, s+2, s+1, s}, ***p;
      p = ptr;
      ++p; 
      printf("%s",*--*++p + 3); 
}

What will be the output of the following C code?

#include<stdio.h>
main()
{
    int n;
    n=f1(4);
    printf("%d",n);
}
f1(int x)
{
    int b;
    if(x==1)
        return 1;
    else
        b=x*f1(x-1);
        return b;
}

In the absence of a exit condition in a recursive function, the following error is given . . . . . . . .

What is the output of this C code?

#include <stdio.h>
main()
{
    if (sizeof(int) > -1)
        printf("True");
    else
        printf("False");
}

What will be the value of the following assignment expression?

(x = foo())!= 1 considering foo() returns 2

Suppose we have: int a=100; (signed by default).
If we want to convert this to an unsigned long integer, we can do this by making the following small change:

Suppose we transfer a file written on a little endian machine to a big endian machine and there is no transformation from little endian to big endian, then what happens?

File formats which have . . . . . . . . as a basic unit are independent of endianness.

What will be the output of the following C code?

#include<stdio.h>
static inline int max(int a, int b) 
{
  return a > b ? a : b;
}
main()
{
    int m;
    m=max(-6,-5);
    printf("%d",m);
}

Sign qualifiers can be applied to double.

What is the output of this C code?

#include <stdio.h>
main()
{
    char *p = "Examveda C-Test";
    p[0] = 'a';
    p[1] = 'b';
    printf("%s", p);
}

The following C code results in an error. State whether this statement is true or false.

#include <stdio.h>
void f(double b) 
{
    printf ("%ld\n",b);
}
int main() 
{
     inline f(100.56);
     return 0;
}

What will be the output of the following C code?

main()
{
    unsigned a=10;
    long unsigned b=5l;
    printf(“%lu%u”,a,b);
}

What is the binary representation of the integer -14?

Functions in C Language are always . . . . . . . .

What will be the error in the following C code?

main()
{
    long float a=-25.373e22;
    printf("%lf",a);
}
