杭电ACM A+B for Input-Output Practice (I-VIII))C语言答案解析

今天做了一些杭电ACM的题，不得不说，做了这些题才发现自己实在基础太过薄弱了，还是得多加练习。在这里分享一下自己的答案吧。

1.1.1A+B for Input-Output Practice (I)

#include<stdio.h>
int main()
{
int a, b;
while (scanf("%d%d", &a, &b) != EOF)//需要多次验证==也可以写成while (scanf("%d %d", &a,&b) == 2)
printf("%dn", a + b);
return 0;
}

1.1.2A+B for Input-Output Practice (II)

#include<stdio.h>
int main()
{
int a, b, n;
int i = 0;
scanf("%d", &n);
while (i < n)
{
scanf("%d %d", &a, &b);
printf("%dn", (a + b));
i++;
}return 0;
}

1.1.3A+B for Input-Output Practice(III)

#include<stdio.h>
int main()
{
int a, b;
while (scanf("%d %d",&a,&b) == 2)
{
if (a == b && a == 0)exit();
printf("%dn", (a + b));
}
return 0;
}

1.1.4A+B for Input-Output Practice(IV)

#include<stdio.h>
int main()
{
int n, i;
int sum=0;
while(1)
{
scanf("%d", &n);
if (n == 0)exit();
while (n != 0)
{
scanf("%d", &i);
sum = sum + i;
n--;
}
printf("%dn", sum);
sum = 0;
}
return 0;
}

1.1.5A+B for Input-Output Practice(V)

#include<stdio.h>
int main()
{
int n, i,m;
int sum = 0;
scanf("%d",&m);
while (m>0)
{
scanf("%d",&n);
while (n != 0)
{
scanf("%d",&i);
sum = sum + i;
n--;
}
printf("%dn", sum);
sum = 0;
m--;
}
return 0;
}

1.1.6A+B for Input-Output Practice(VI)

#include<stdio.h>
int main()
{
int n, i = 0;
int sum = 0;
while (scanf("%d", &n) != EOF)
{
while (n > 0)
{
scanf("%d", &i);
sum = sum + i;
n--;
}
printf("%dn", sum);
sum = 0;
}
return 0;
}

1.1.7A+B for Input-Output Practice(VII)

#include<stdio.h>//无意义的弱智抠字眼题
int main()
{
int a, b;
while (scanf("%d %d", &a, &b) != EOF)
printf("%dnn", (a + b));
return 0;
}

1.1.8A+B for Input-Output Practice(VIII)

#include<stdio.h>
int main()
{
int n, a[100], sum, m, i;
scanf("%d", &n);
while (n--)
{
sum = 0;
scanf("%d", &m);
for (i = 1; i <= m; i++)
{
scanf("%d", &a[i]);
sum = sum + a[i];
}
if (n != 0)
printf("%dnn", sum);
if (n == 0)
printf("%dn", sum);
}
}
