8. main(){
int i;
i=1,2,3,4;
printf(“%d”,i);
}
output: 1
i=1 is one expression. After that 2, 3, 4 are taken as three statemets. C will ignore those three.
9. Is this code correct? If not, suggest possible modifications.
main(){
int i,j;
i=10; j=20;
i > j ? i : j = 0;
printf(“i=%d, j=%d”,i,j);
}
Output: Lvalue required
Modify the expression as *(i > j ? i : j) = 0;
The larger one will be assigned to zero.
10. main(){
int a[10],i;
for(i=0;i<10;i++)
scanf(“%d”&a[i]);
for(i=0;i<10;i++)
printf(“%d”,i[a]);
}
input : 1 2 3 4 5 6 7 8 9 1
output : 1 2 3 4 5 6 7 8 9 1
a[i] and i[a] are similar
11. main(){
char *p;
gets(p);
puts(p);
}
Output: segmentation fault.
We are using the pointer without allocating memory
