九九乘法有点小错，麻烦帮我看一下
#include <stdio.h>
void main()
{
int a=1,b,num;
while (a <10)
{
b=1;
while (b <=a)
{
b++;
num=a*b;
printf( "%d*%d=%-5d ",a,b,num);
};
printf( "\n ");
a++;
}
}

[解决办法]
#include <stdio.h>
#include <stdlib.h>
int main()
{
int a=1,b,num;
while (a <10)
{
b=0;
while (b <a)
{
b++;
num=a*b;
printf( "%d*%d=%-5d ",a,b,num);
};
printf( "\n ");
a++;
}
system( "pause ");
}

[解决办法]
#include "stdafx.h "
#include <stdio.h>

int main(int argc, char* argv[])
{
int a=1,b,num;
while (a <10)
{
b=1;
while (b <=a)
{
num=a*b;
printf( "%d*%d=%-5d ",a,b,num);
b++;
};
printf( "\n ");
a++;
}
}
b++放在后面就OK！
