如何實(shí)現(xiàn)：sum實(shí)現(xiàn)1到m的累加，mul實(shí)現(xiàn)1到n累乘？

然后在主函數(shù)main里調(diào)用sum和mul函數(shù)求1到30累加和1到15累乘，最后把累加和累乘結(jié)果輸出你這是用什么方法啊，頭文件和主函數(shù)名都沒(méi)有啊

private int CountSum(int pintSum)
{
int intSum = 0;
for(int intIndex=1;intIndex <=pintSum;intIndex ++)
{
intSum = intSum + intIndex;
}
return intSum;
}

private long CountMul(int pintMul)
{
long intMul = 1;
for (int intIndex = 1; intIndex <= pintMul; intIndex++)
{
intMul = intMul * intIndex;
}
return intMul;
}

在主函數(shù)中調(diào)用時(shí):
CountSum(30);
CountMul(15);
