Answer 1

int main()
{
int i,j;
for(i=1;i<=9;i++)
{
for(j=1;j<=i;j++)
printf("念逗%d*%d=%d "仔坦卖,j,i,j*i);
printf("\信脊n");
}
return 0;
}

Answer 2

int main()
{
    int i,j;
    for(i=1;i<10;i++)
    {
        for(j=1;j<=i;j++)
       搜此 {
            printf("%dx%d=%2d ",j,i,i*j);
        世闹迅}
        printf("\n");
