九九乘法表的打印
附上源代码
#include<stdio.h>
int main()
{
int a, b, c;
for (a = 1; a <= 9; a++)
{
for (b = 1; b <= a; b++)
{
c = a * b;
printf("%d*%d=%d “, a, b, c);
}
printf(”\n");
}
}
我们还可以给定一个值num，打印这个值的乘法表，用例为12
#define _CRT_SECURE_NO_WARNINGS 1
#include<stdio.h>
int main()
{
int a, b, c, num;
printf(“请输入一个数字：”);
scanf("%d", &num);
for (a = 1; a <= 9; a++)
{
for (b = 1; b <= a; b++)
{
c = a * b;
printf("%d*%d=%d “, a, b, c);
}
printf(”\n");
}
}
