Include <math.h>

main{}

(

FLOAT  X;

X = 2.5 ;

Y = exp(x) ;

Print(x,y);

)

14. Find the output of the program :

#include<stdio.h>

void main()

{

int x=3,y=5,z=7,w;

w=x%y + y%x - z%x - x %z;

printf(“%d\n”,w);

w=x/z + y/z + (x+y)/z;

printf(“%d”,w);

}

15.Find the output of the program :

#include<stdio.h>

void main()

{

int x=3,y=5,z=7,w=9;

w += x + y -( z -= w );

printf(“w=% d, z=%d\n”,w,z);

w += x -= y %= z;

printf(“w=%d, y=%d, z=%d”,w,y,z);

}

16. Find the output of the program :

#include<stdio.h>

void main()

{

int x=3,y=5;

x = y++ + x++;

y = ++y + ++x;

printf(“x=% d, y=%d”,x,y);

}
