計算字元的字串程式

實施

現在，我們將瞭解程式的實際實施 -

#include <stdio.h>

int main() {
   char s[] = "TajMahal";     // String Given
   char ch = 'a';             // Character to count
	
   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;
}

輸出

此程式的輸出應為 -

a appears 3 times in 'TajMahal'
