1) printf(“%s”,str); // or the more curt one
2) printf(str); | | 1 | | main()
{
int a=10,*j;
void *k;

} | | 1 | | Is there any difference between the two declarations,
1. int foo(int *arr[]) and
2. int foo(int *arr[2]) | | 1 | | print numbers till we want without using loops or condition
statements like specifically(for,do while, while swiches,
if etc)!
