Question

请问C语言写一个求 1 ~100的 累加求和运算！~

Answer 1

#include<stdio.h>
int main()
{
int i;
int sum = 0;
for (i = 1; i <= 100; ++i)
{
sum += i;//1到100累加
}
printf("%d\n", sum);//输出结果

return 0;
}

Answer 2

#include<stdio.h>
int main()
{

int sum = 0;

for (int i = 1; i <= 100; i++)
{
sum += i;
}
printf("%d\n", sum);

return 0;
}

Answer 3

main(){
int result=0;
for(int i=0;i<=100;i++){
result+=i;
}
printf("%d",result);
}

Answer 4

#include<stdio.h>
int main()
{
int sum = 0;
for (int i = 1; i <= 100; i++)
{
sum += i;
}
printf("%d\n", sum);
return 0;
}
呵呵！

Answer 5

#include <stdio.h>

int main(){
int i = 100;
int sum = 0;
while(i-- >= 0){
sum += (i + (100 - i))/2 ;
}
printf("你要的和是:%d\n",sum);
return 0;
}
