输出的是32?为什么?
#include<stdio.h>main()
{
int bph2o=212;
int rv;
rv=printf("%d F is water boiling point.\n",bph2o);
printf("The printf() function printed %d characters.\n",rv);
}
#include<stdio.h> int main() { int bph2o=212; int rv; rv=printf("%d123456789",bph2o); printf("\n%d",rv); return 0; }也许你这样测试 效果会好一些
