输入一个字符串，再输入一个字符，统计该字符出现的次数c语言

#include <stdio.h>
#include <string.h>

int main()
{
char str[100], ch;
int count = 0;

printf("Enter a string: ");
gets(str);

printf("Enter a character: ");
scanf("%c", &ch);

for(int i=0; i<strlen(str); i++)
{
if(str[i] == ch)
count++;
}

printf("The character '%c' appears %d times in the string.", ch, count);

return 0;
}
