c语言 4-22 显示出一个横向较长的长方形

1、for语句

#include <stdio.h>

int main(void)
{
    int i, j, side1, side2;
    puts("please input the sides.");
    do
    {
        printf("side1 = "); scanf("%d", &side1);
        printf("side2 = "); scanf("%d", &side2);
        if (side1 == side2)
            puts("side1 == side2!");
    }
    while (side1 == side2);
    
    if (side1 >= side2)
    {
        for(i = 1; i <= side2; i++)
        {
            for(j = 1; j <= side1; j++)
            {
                putchar('*');
            }
            putchar('\n');
        }
    }
    else
    {
        for(i = 1; i <= side1; i++)
        {
            for(j = 1; j <= side2; j++)
            {
                putchar('*');
            }
            putchar('\n');
        }
    }
    return 0;
}

2、for语句

#include <stdio.h>

int main(void)
{
    int i, j, side1, side2, shorter, longer;
    puts("please input the sides.");
    do
    {
        printf("side1 = "); scanf("%d", &side1);
        printf("side2 = "); scanf("%d", &side2);
        if(side1 == side2)
            puts("side1 == side2!");
    }
    while(side1 == side2);
    
    shorter = side1 > side2 ? side2:side1;
    longer  = side1 > side2 ? side1:side2;
    
    for(i = 1; i <= shorter; i++)
    {
        for(j = 1; j <= longer; j++)
        {
            putchar('*');
        }
        putchar('\n');
    }
    return 0;
}

#include <stdio.h>

int main(void)
{
    int i, j, height, width, tmp;
    puts("please input the height and width.");
    do
    {
        printf("height = "); scanf("%d", &height);
        printf("width = "); scanf("%d", &width);
        if (height == width)
            puts("height == width!");
    }
    while (height == width);
    
    if (height > width)
    {
        tmp = height;
        height = width;
        width = tmp;
    }
    
    for(i = 1; i <= height; i++)
    {
        for(j = 1; j <= width; j++)
        {
            putchar('*');
        }
        putchar('\n');
    }
    return 0;
