Question

现在我们来了解条件跳转。

#!cpp
#include <stdio.h>

void f_signed (int a, int b)
{
    if (a>b)
        printf ("a>b
");
    if (a==b)
        printf ("a==b
");
    if (a<b)
        printf ("a<b
");
};

void f_unsigned (unsigned int a, unsigned int b)
{
    if (a>b)
        printf ("a>b
");
    if (a==b)
        printf ("a==b
");
    if (a<b)
        printf ("a<b
");
};

int main()
{
    f_signed(1, 2);
    f_unsigned(1, 2);
    return 0;
};
