Answer 1

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

void capitalizeString(char* str) {
    int i;

    // 将字符串转换为小写
    for (i = 0; str[i]; i++) {
        str[i] = tolower(str[i]);
    }

    // 将开头字母转换为大写
    str[0] = toupper(str[0]);
}

int main() {
    char name[] = "ZHANG SAN";

    printf("原始字符串: %s\n", name);

    capitalizeString(name);

    printf("转换后的字符串: %s\n", name);

    return 0;
