如何在C中复制字典

typedef struct {
    char key[50];
    int value;
} KeyValuePair;

KeyValuePair originalDict[] = {
    {"key1", 1},
    {"key2", 2},
    {"key3", 3}
};
int dictSize = sizeof(originalDict) / sizeof(KeyValuePair);

KeyValuePair* copiedDict = malloc(dictSize * sizeof(KeyValuePair));

for (int i = 0; i < dictSize; i++) {
    strcpy(copiedDict[i].key, originalDict[i].key);
    copiedDict[i].value = originalDict[i].value;
}

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

typedef struct {
    char key[50];
    int value;
} KeyValuePair;

int main() {
    KeyValuePair originalDict[] = {
        {"key1", 1},
        {"key2", 2},
        {"key3", 3}
    };
    int dictSize = sizeof(originalDict) / sizeof(KeyValuePair);

    KeyValuePair* copiedDict = malloc(dictSize * sizeof(KeyValuePair));

    for (int i = 0; i < dictSize; i++) {
        strcpy(copiedDict[i].key, originalDict[i].key);
        copiedDict[i].value = originalDict[i].value;
    }

    // 打印复制后的字典
    for (int i = 0; i < dictSize; i++) {
        printf("Key: %s, Value: %d\n", copiedDict[i].key, copiedDict[i].value);
    }

    free(copiedDict); // 释放动态分配的内存

    return 0;
}
