c - 如何读取c中换行后出现的整数？

Question

int fscanf(FILE *stream, const char *format, ...);

我可以使用fscanf()从文件中读取整数。如何读取换行符后面的整数？

Answer 1

fscanf() - 看一下例子。

这就是您想要的:

#include <stdio.h>

int main()
{
    int n;
    FILE * pFile;

    pFile = fopen("myfile.txt", "r");

    // Repeat this as many times as necessary
    fscanf(pFile, "\n%d", &n);
    printf("%d\n", n);

    fclose(pFile);

    return 0;
}
