请分别用while do....while和for三种循环语句编写程序1+3+5+7+......101

int sum=0,i;
for(i=1;i<102;i+=2)
sum+=i;

sum=0;
while(i<=101)
{
sum+=i;
i+=2;
}

sum=0;
i=1;
do
{
sum+=i;
i+=2;
}while(i<101)

int i =1; int sum=0; while(i<=101) {     sum+=i;     i+=2; } 输出 sum的值就是结果 --------------------------- int i=1; int sum =0; do {    sum+=i;    i+=2; } while(i<=101) ------------------------ int sum=0; for(int i=1;i<=101;i+=2) {     sum+=i; }
