VC如何把变量写入文件txt里？

我的main函数里已经有了int a，float b[10]，char c[5][5]，一共三个东西，都已经赋好了值，现在要把他们写到文件里：xx.txt，各占一行一共三行，该如何写？

Answer 1

fp = fopen("xx.txt", "w");
fprintf(fp, "%d\n", a);
for ( i = 0; i < 10; ++i ) fprintf(fp, "\t%d",b[i]);
fprintf(fp, "\n");
for (i =0; i < 5; ++i )
for (j = 0; j < 5; ++j )
fprintf(fp, "\t%d", c[i][j]);
fprintf(fp, "\n");
fclose(fp);
