如何从c中的文件读取特定数据列

FILE *file = fopen("file.txt", "r");

char line[100];
while (fgets(line, sizeof(line), file)) {
    int column1, column2;
    sscanf(line, "%d %d", &column1, &column2);
    printf("Column 1: %d, Column 2: %d\n", column1, column2);
}

fclose(file);

#include<stdio.h>

int main() {
    FILE *file = fopen("file.txt", "r");
    if (file == NULL) {
        printf("Error: Cannot open file.\n");
        return 1;
    }

    char line[100];
    while (fgets(line, sizeof(line), file)) {
        int column1, column2;
        sscanf(line, "%d %d", &column1, &column2);
        printf("Column 1: %d, Column 2: %d\n", column1, column2);
    }

    fclose(file);
    return 0;
}
