Answer 1

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

int main() {
    char str1[] = "I am a student of Anhui University.";
    int length = strlen(str1);
    printf("字符串长度为：%d\n", length);

    for (int i = 0; i < length; i++) {
        if (str1[i] == 'a' || str1[i] == 'A') {
            str1[i] = ' ';
        }
    }

    printf("替换后的字符串为：%s\n", str1);

    return 0;
}

按照样例来的话

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

int main() {
    char str1[] = "I am a student of Anhui University.";
    int length = strlen(str1);
    printf("%d\n", length);

    for (int i = 0; i < length; i++) {
        if (str1[i] == 'a' || str1[i] == 'A') {
            str1[i] = ' ';
        }
    }

    printf("%s\n", str1);

    return 0;
}
