c - C语言如何交替显示两个字符串字符

Question

例如:s1 = "ABC"

s2 = "qwerty"

s3 将是“AqBwCerty”

全部为大写字母

它将是“AQBWCERTY”

如何创建？

谢谢~

这是我当前在主函数中的代码:

char w[100];
char s[50] = "abcderf";
char t[50] = "ARTYY";
int len = strlen(s);
int len1 = strlen(t);
int i, j;
if (len > len1) {
    t[50] + s[50];
}
printf("%s", w);

像这样尝试:

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

char* interleaveStr(char* s1, char* s2) {
    char* space = malloc(strlen(s1) + strlen(s2) + 1);
    char* newStr = space;
    int turn = 0;
    while (*s1 && *s2) {
        *newStr++ = !turn ? *s1++ : *s2++;
        turn = !turn;
    }

    while (*s1) {
        *newStr++ = *s1++;
    }
    while (*s2) {
        *newStr++ = *s2++;
    }
    *newStr = '\0';
    return space;
}

int main() {
    char* s1 = "ABC";
    char* s2 = "qwerty";
    char* inter = interleaveStr(s1, s2);
    printf("%s\n", inter);
    free(inter);
}
