用于计数字符的字符串程序

实施

现在，我们将看到程序的实际实施 −

#include <stdio.h>

int main() {
   char s[] = "TajMahal";     // 给定字符串
   char ch = 'a';             // 字符计数
	
   int i = 0;
   int count = 0;             // Counter
      
   while(s[i] != '\0') {
      if(s[i] == ch)
         count++;

      i++;
   }
   
   if(count > 0) {
      if(count == 1)
         printf("%c appears %d time in '%s'", ch, count, s);
      else
         printf("%c appears %d times in '%s'", ch, count, s);
   } else
      printf("%c did not appear in %s", ch, s);
   
   return 0;
}

输出

此程序的输出应为 −

a appears 3 times in 'TajMahal'
