下面程序段的运行结果是()。#include stdio.hmain(){int m=10 n=20char *format=\%s m=%d n=%d\nm*=nprintf(format m*=n m n)}

下面程序段的运行结果是()。#include "stdio.h"main(){int m=10, n=20char *format="%s, m=%d, n=%d\n"m*=nprintf（format, "m*=n", m,n)}

A.format, "m*=n", m, n

B.format, "m*=n"

C.m*=n, m=200, n=20

D.以上结果都不对

请帮忙给出正确答案和分析，谢谢！
