用c语言连接两个字符串字符串用键盘输入。不调用函数

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

int main() { char str1[100], str2[100], result[200]; int i, j;

printf("Enter the first string: ");
scanf("%s", str1);

printf("Enter the second string: ");
scanf("%s", str2);

// Copying the first string to the result array
for (i = 0; str1[i] != '\0'; i++) {
    result[i] = str1[i];
}

// Concatenating the second string to the result array
for (j = 0; str2[j] != '\0'; j++) {
    result[i + j] = str2[j];
}

// Null terminating the result array
result[i + j] = '\0';

printf("The concatenated string is: %s\n", result);

return 0;

}
