C语言视频

#include<stdio.h>
int main()
{

    double foot;
    double inch;
    printf("请输入身高的英尺英寸: ");
    scanf("%lf %lf",&foot,&inch);
    printf("身高%f米\n",((foot+inch/12)*0.3048));//英文输入法
    return 0;
}

 

2、算时间差

#include<stdio.h>
int main()
{
    int hour1,minute1;
    int hour2,minute2;
    scanf("%d %d",&hour1,&minute1);    
    scanf("%d %d",&hour2,&minute2);
    int t1=hour1*60+minute1;
    int t2=hour2*60+minute2;
    int t=t2-t1;
    printf("时间差是%d小时%d分钟",t/60,t%60);
}

 

3、整数的四则运算

#include<stdio.h>
int main()
{
    int a,b;
    scanf("%d %d",&a,&b);
    printf("a+b=%d\n",a+b);
    printf("a-b=%d\n",a-b);
    printf("a*b=%d\n",a*b);
    printf("a/b=%d\n",a/b);
    return 0;
}
