简写。
如果在输入的字符串中,含有类似于4—8的字串,我们就把它当作一种数字串的简写,输出时,用连续的数字串替代其中的’—’号。即将上面子串输出为45678.
例如:用户输入: as —2df0—8we,则输出: as —2df012345678we.若用户输入:9—2abc8,则输出:98765432abc8
哈喽，代码如下，有用请点采纳哦
#include<stdio.h>
int main()
{
char c1[100] = { '\0' };
int i=0;
printf("请输入字符串\n");
gets(c1);
char left;
char right;
while(c1[i]!='\0')
{
if(i==0){
printf("%c", c1[i]);
i++;
continue;
}
char start = c1[i-1];
char end = c1[i+1];
if (c1[i] == '-' && start >='0' && start<='9' && end >='0' && end<='9')
{
if(start>end){
start--;
for(;start>end;start--){
printf("%c", start);
}
}else{
start++;
for(;start<end;start++){
printf("%c", start);
}
}
}else{
printf("%c", c1[i]);
}
i++;
}
}
