整数转换为字符串

string字符串 “ ”

char单个字符 ‘ ’

=================version_init===========================

#include <stdio.h>
int main(){
int n,sum =0;
int gw,sw,bw,qw;
char save[]={'ling','yi','er','san','si','wu','liu','qi','ba','jiu','shi'};
while(scanf("%d",&n)!=EOF){
sum +=n;//最多是四位数字
}
gw = sum%10;
sw = sum/10%10;
bw = sum/100%10;
qw = sum/1000%10;
if(qw != 0)
printf("%c\n%c\n%c\n%c",&save[qw],&save[sw],&save[bw],&save[qw]);
    else if(bw != 0)
printf("%c\n%c\n%c",&save[qw],&save[sw],&save[bw]);
    else if(sw != 0)
printf("%c\n%c",&save[qw],&save[sw]);
    else if(qw != 0)
printf("%c\n%c",&save[qw]);
return 0;
}
========================

for (int i = 0; i < s.length(); i++)
        sum += (s[i] - '0');
    string num = to_string(sum);
    for (int i = 0; i < num.length(); i++) {
        if (i != 0) cout << " ";
cout << str[num[i] - '0'];

不知道这些函数都是怎么用！！！！！！！！

sum += (s[i] - '0');

string num = to_string(sum);

for (int i = 0; i < num.length(); i++) {

if (i != 0) cout << " ";

cout << str[num[i] - '0'];

for (int i = 0; i < s.length(); i++)
