这道题怎么写呢？

Answer 1

#include<stdio.h>
#include <string.h>
int findLetter(char str){
int i; //该字母在元素的位置
char letter[26]={'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'};
if((int)str>=97&&(int)str<=122){
str=(char)((int)str-32);
}
for(i=0;i<26;i++){
if(str==letter[i]){
break;
}
}
i++;
return i;
}
void main(){
int i,sum=0;
char str[100000];
printf("请输入单词和词组：");
gets(str);
for(i=0;i<strlen(str);i++){
if(findLetter(str[i])<=26){
sum+=findLetter(str[i]);
}
}
printf("1. %d[]\n",sum);
}

Answer 2

#include<stdio.h>
int main() {
int sum=0,ch;
while((ch=getchar())!='\n')
{
if(ch>='a' && ch <='z') ch=ch-'a'+'A';
if(ch>='A' && ch<='Z') sum+=ch-'A'+1;
}
printf("%d",sum);
}
