这是我的代码，但我不知道如何将值插入到不同的数组中

#include <stdio.h>
#include <string.h>
int main (){

    char word[100], cutword[50];
    int on, off, i, j;

    printf("Entra a word: ");
    gets(word);
    printf("Enter a postion to know where to start cutting: ");
    scanf("%d", &on);
    printf("Enter the following quantity to end up: ");
    scanf("%d", &off);

    for (i = 0; i<strlen(word); i++){
        if (i >= on && i <= off) ¿cutword[]? = word[i];
    }

    for (j = 0; j<strlen(cutword); j++){
        printf("%c", cutword[j]);
    }

}

Answer 1

int k = 0;
int l = on + off;
for (i = on; i < l; i++){
    cutword[k++] = word[i];
}

for (j = 0; j < k; j++){
    printf("%c", cutword[j]);
}

添加一些额外的 if在这些循环之前验证输入并检查数组边界。
