通过#include将char文件内容分配给char数组

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

int main() {
    char *filename = "myfile.txt";
    char *buffer;
    int length;

    // 打开文件
    FILE *fp = fopen(filename, "r");
    if (fp == NULL) {
        printf("Error opening file
");
        return 1;
    }

    // 获取文件长度
    fseek(fp, 0, SEEK_END);
    length = ftell(fp);
    fseek(fp, 0, SEEK_SET);

    // 分配内存
    buffer = (char*) malloc(length);
    if (buffer == NULL) {
        printf("Error allocating memory
");
        return 1;
    }

    // 读取文件内容到内存
    fread(buffer, length, 1, fp);
    fclose(fp);

    // 打印文件内容
    printf("File content:
%s
", buffer);

    // 释放内存
    free(buffer);

    return 0;
}
