Hi,

If the variable 'p' in printf statement is replaced by array name 'a', then we get the output as option 'A'.

Could anyone explain this discrepancy?

Please explain this question how the compiler works?

Please, anybody explain this concept and tell the answer for it.

#include
void main()
{
int a[2][2]={{2},{3}};
printf("%d",a[0][0]);
printf("%d",a[0][1]);
printf("%d",a[1][0]);
printf("%d",a[1][1]);
}
