用c语言从键盘输入两个数字,判断哪个数更大？

Posted 2023-05-05

参考技术A 算法思路:

从控制台输入得到两个整数(或者实数，看你的需要)a，b

如果a>b，输出"a大于b"

否则，如果a=b，输出""a等于b"

否则，输出"a小于b"

核心代码:

if(a>b)printf("a大于b");

else if(a==b)printf("a等于b");

else printf("a小于b"); 参考技术B #include <stdio.h>
int main()
int num1, num2;
printf("请输入两个数字：\n");
scanf("%d %d", &num1, &num2);
if (num1 > num2)
printf("%d 更大\n", num1);

else if (num2 > num1)
printf("%d 更大\n", num2);

else
printf("两个数字相等\n");

return 0;

该程序使用scanf()函数从键盘读取两个数字，并使用条件语句比较它们的大小。如果num1大于num2，则输出num1更大；如果num2大于num1，则输出num2更大；如果两个数字相等，则输出“两个数字相等”。
