写一个函数讲一个字符串使用特定的分隔符分割后输出

#include <stdio.h>

int main(){
char* p = NULL;
char s[100] ;

int i = 0;

scanf("%s",s);
p = s;
printf("%s\n",p);
char a ;
int count = 0 ;

while((a = *p++) !='\0'){
if(a ==':'){
count++;
}
}

p = s;

int count1 = 0;

while((a = *p++)!='\0'){
i++;

if(a == ':'){
count1++;

int j ;
for(j = -i; j < -1 ; ++j){
printf("%c",p[j]);
}
printf("\n");

if(count == count1){
printf("%s\n",p);
return 0;
}

i = 0;
}

}
}
