int main()
{
 printf("Storage size for char : %d \n", sizeof(char));
 printf("Storage size for int : %d \n", sizeof(int));

}

output :
Storage size for char : 1

Storage size for float : 4
Storage size for double : 8
Minimum float positive value: 1.175494E-038
Maximum float positive value: 3.402823E+038
