//用do while语句
#include
int main()
{
int i=1;
int sum=0;
do{
sum+=i;
i+=2;
}while(i<=99);
printf("100以内奇数和为sum=%d\n",sum);
return 0;
}
//用for语句
#include
int main()
{
int i,n;
int sum=0;
for(i=1;i<=50;i++){
n=2*i-1;
sum=sum+n;
}
printf("100以内奇数和为sum=%d\n",sum);
return 0;
}
//用while语句
#include"stdio.h"
int main()
{
int i=1,n;
int sum=0;
while(i<=100)
{
if(i%2==0)//判断奇偶性
sum=sum+(i-1);
i++;
}
printf("100以内奇数和为sum=%d\n",sum);
return 0;
}

//判断是否为奇数
int sum=0;
for(int i=1;i<100;i++)
{
if(i%2==0)
sum+=i;
}
return sum
int sum=0,i=0;
do
{
if(i%2==0)
sum=sum+i;
i++;
}while(i<=100)
return sum;
int sum=0;
for(int i=1;i<100;i++)
{
if(i%2==0)
sum+=i;
}
return sum
int sum=0,i=0;
do
{
