*a[1]=5;
printf("%d",&a[1]-a)
ANS:
ans may be 1.(illegal initialization)
2)
#include<stdio.h>
main(){
char a[]="hellow";
char *b="hellow";
char c[5]="hellow";

4)
#include<stdio.h>
void function1;
int i-value=100;
main()
{
i-value=50;
function1;
printf("i-value in the function=",i-value);
printf("i-value after the function=",i-value);
}
printf("i-value at the end of main=",i-value);
functioni()
i-value=25;

THIS IS ROUGH IDEA OF THE PROGRAM
ANS ARE
1)i-value in the function=25;
2)i-value after the function=50;
3)i-value at the end of the main=100;

5)
main()
{
funct(int n);
{
switch(n)
case1:
m=2;
break;
case2:
m=5;
break;
case3:
m=7;
break;
default:
m=0;
}
THIS IS ROUGH IDEA:
(ANS:Out put is m=0)
