}
A. 89
B. y
C. Y

Q2.What will be the output of following code
// Assume all header files are included
int
main(void)
{

int
b=432;
int
res;
res=findrem(a,b);
int
findrem(int x,int y)
{
return
x%y;
}
printf("%d",res);
return
0;
}
A. -8
B. 8

a);
}
A. 30
B. 43
C. 0
D. ERROR – Cannot Override Global variable.
Ans : B
Q8.What will be the output of following code
//
Assume all header files are included
#include.....
int
find(int x)
{
return x+2;
}
int
main(void)
{
int a=44;
int res;
res=find(a);
printf("%d",res);
return 0;
}
A. 46
B. 44
C. 0
D. ERROR – res variable can not hold integer value.
Ans : A
Explanation :
find(44) : return (44 + 2)
res = 46
