从C中的行处理数据

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

#define MAX_LINE_LENGTH 1024

int main() {
    char line[MAX_LINE_LENGTH];
    FILE *file = fopen("data.txt", "r");

    if (file == NULL) {
        printf("Error opening file\n");
        return 1;
    }

    while (fgets(line, MAX_LINE_LENGTH, file) != NULL) {
        // 处理每一行数据
        printf("Line: %s", line);
    }

    fclose(file);
    return 0;
}
