Refer to the answer 1:
#include <iostream>#include <string>int main(){ std::string string; std::cin >> string; const char *p = string.c_str(); while (*p) { if (std::isdigit(*p)) { int sum = 0; while (*p && std::isdigit(*p)) sum += *p++ - '0'; std::cout << sum << std::endl; } else { while (*p && !std::isdigit(*p)) std::cout << *p++; std::cout << std::endl; } } return 0;}

Refer to the answer 3:
#include<stdio.h>int main(){ char str[100] = {
'0'}; int flag = 0; int nums = 0; int data = 0; scanf("%s",&str); int n = 0; while (str[n]!='\0') { n++; } for (int i = 0; i < n; i++) { if (str[i]>='a' &&str[i]<='z') { if (flag==1) { printf("%d\n",nums); nums = 0; flag = 0; } printf("%c",str[i]); } if (str[i] >= '1' && str[i] <= '9') { data = str[i] - 48; if (flag==0) { printf("\n"); flag = 1; } } if (flag==1) { nums += data; } } if (flag == 1) { printf("%d\n", nums); } return 0;}
