Question

用c语言求1到100的和

Answer 1

#include<stdio.h>
int main(void)
{
int Sum = 0;

for(int i=1;i<=100;i++)
{
Sum +=i;
}

printf("%d",Sum);
}

Answer 2

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

建议你自己多换几个别的方式输出试试。

Answer 3

#include <stdio.h>

void main()
{
int sum = 0;
for(int n = 1; n <= 100; n++)
sum += n;

printf("1 + 2 + 3 + ... + 100 = %d\n", sum);
}

Answer 4

#include<stido.h>
void main()
{int sum=0,i;
for(i=1;i<=100;i++)
sum+=i;
printf("%d",sum);
}

Answer 5

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