プログラムテスト

#include 

int main()
{
    int size_char   = sizeof(char);
    int size_int    = sizeof(int);
    int size_short   = sizeof(short);
    int size_double = sizeof(double);
    int size_float  = sizeof(float);

    printf("size of char: %d\r
", size_char);
    printf("size of int: %d\r
", size_int);
    printf("size of short: %d\r
", size_short);
    printf("size of double: %d\r
", size_double);
    printf("size of float: %d\r
", size_float);

    return 0;
}
