使用C编程查找字符串中子字符串的出现次数

int countSubstring(const char* str, const char* subStr);

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

int countSubstring(const char* str, const char* subStr) {
    int count = 0;
    int subStrLen = strlen(subStr);

    while (*str != '\0') {
        if (strstr(str, subStr) != NULL) {
            count++;
            str += subStrLen;
        } else {
            str++;
        }
    }

    return count;
}

int main() {
    const char* str = "ababababab";
    const char* subStr = "aba";
    int result = countSubstring(str, subStr);

    printf("子字符串 \"%s\" 在字符串 \"%s\" 中出现的次数为：%d\n", subStr, str, result);

    return 0;
}
