99乘法表 while循环版

#include <iostream> #include <string> using namespace std ; int main(){ int i=1; int m=1; while(i<10){ while(m<=i){ int j=m*i; cout<<m<<"*"<<i<<"="<<j<<" "; ++m; } cout<<endl; ++i; m=1; } return 0; }

可以使用两个嵌套的while循环来打印99乘法表，具体代码如下： ```python i = 1 while i <= 9: j = 1 while j <= i: print("%d * %d = %d" % (j, i, i*j), end='\t') j += 1 print() i += 1 ``` 输出结果如下： ``` 1 * 1 = 1 1 * 2 = 2 2 * 2 = 4 1 * 3 = 3 2 * 3 = 6 3 * 3 = 9 1 * 4 = 4 2 * 4 = 8 3 * 4 = 12 4 * 4 = 16 1 * 5 = 5 2 * 5 = 10 3 * 5 = 15 4 * 5 = 20 5 * 5 = 25 1 * 6 = 6 2 * 6 = 12 3 * 6 = 18 4 * 6 = 24 5 * 6 = 30 6 * 6 = 36 1 * 7 = 7 2 * 7 = 14 3 * 7 = 21 4 * 7 = 28 5 * 7 = 35 6 * 7 = 42 7 * 7 = 49 1 * 8 = 8 2 * 8 = 16 3 * 8 = 24 4 * 8 = 32 5 * 8 = 40 6 * 8 = 48 7 * 8 = 56 8 * 8 = 64 1 * 9 = 9 2 * 9 = 18 3 * 9 = 27 4 * 9 = 36 5 * 9 = 45 6 * 9 = 54 7 * 9 = 63 8 * 9 = 72 9 * 9 = 81 ```
