这些都是基本的 C 程序,可以帮助刚踏入 C 编程世界的新手。快来试试吧:
1、C 语言编程 – Hello World
#include<stdio.h>
int main()
{
printf("Hello world\n");
printf("Linux迷 www.linuxmi.com");
return 0;
}
2. C 语言编程 - 执行算术运算
#include<stdio.h>
int main()
{
int a,b;
printf("Enter two numbers:");
scanf("%d%d",&a,&b);
printf("Sum=%d difference=%d product=%d quotient=%d\n",a b,a-b,a*b,a/b);
return 0;
}
3.C 编程 - 求圆的面积
#include<stdio.h>
#include<math.h>
int main()
{
float r;
float N=3.14;
float s;
//N*r*r;该行必须在输入r值以后
printf("请输入该圆的半径:");
scanf("%f",&r);
s=N*r*r;
printf("%.7f\n",s);//输出小数点后7位
return 0;
}
4.C编程 - 在3个数字中找到最大值
#include<stdio.h>
int main()
{
int a, b, c;
printf("\nEnter value of a, b & c : ");
scanf("%d %d %d", &a, &b, &c);
if ((a > b) && (a > c))
printf("\na is greatest\n");
if ((b > c) && (b > a))
printf("\nb is greatest\n");
if ((c > a) && (c > b))
printf("\nc is greatest\n");
return 0;
}
5.C编程 - 查找偶数或奇数
#include<stdio.h>
int main()
{
int n;
printf("Enter a number:");
scanf("%d",&n);
if(n%2==0)
{
printf("Number is even\n");
}
else
{
printf("Number is odd\n");
}
return 0;
}
