主要考察double類型的輸入輸出
#include <stdio.h>#include <stdlib.h>/* run this program using the console pauser or add your own getch, system("pause") or input loop */int main(int argc, char *argv[]) { double r; while(scanf("%lf",&r)!=EOF) { if(r>0) printf("%.2lf/n",r); else printf("%.2lf/n",-r); } return 0;}新聞熱點(diǎn)
