Question

如何用do…while循环输出九九乘法表？

Answer 1

#include<stdio.h>
void main()
{
int a,b;
a=b=1;
do
{do<br> {printf(" %d*%d=%d ",a,b,a*b);<br> b++;}
while(b<=9);
printf("\n");
a++,b=1;
}
while(a<=9);
}

Answer 2

#include<stdio.h>
void main()
{
int i=1, j=1;

do
{
j=1;
do
{
printf("%dx%d=%d\t",j,i,i*j);
j++;

}while(j<=i);

i++;
printf("\n");

}while(i<=9);

}

Answer 3

int i=1,j=1;do{printf("%d",j*i++);if(i==10){i=1;j++;}}while(j!=9);
