C language-nine to nine multiplication table

Nine-nine multiplication table-C language implementation

With the help of C language loop to realize the multiplication table of nine to nine, the formatted positive sequence is required to be displayed on the terminal.

#include<stdio.h> 
//借助for（）的两层循环，外循环决定*左边的数，内循环决定*右部的数。
//内循环每执行一次输出一次并用'\t'格式化水平制表。
//内循环结束进行换行。
int main()
{
    
    
	int i, j;

	for (i = 1; i < 10; i++)
	{
    
    
		for (j = 1; j <= i; j++)
		{
    
    
			printf("%d*%d=%d",i,j,i*j);
			putchar('\t');
		}
		putchar('\n');
	}
	return 0;
}

This topic mainly examines the use of loops, which can be easily achieved with the help of for loop nesting.
Error-prone point: the end of the inner loop is linked to the end condition of the outer loop.
