我来开先例吧 #include<stdio.h> #include<stdlib.h> void main() { FILE *finput,*foutput; int c,temp,i,total; float avg,sum=0; printf("Input the number of the numbers:"); scanf("%d",&total); finput=fopen("input.txt","w+"); if(finput != NULL) { for(i=0;i<total;i++) { temp=rand(); printf(" %d \n",temp); fprintf(finput,"%d\n",temp); } } else printf("Error 01:Couldn't open input.txt in writing phase."); fclose(finput); finput=fopen("input.txt","r+"); if(finput != NULL) { foutput=fopen("output.txt","w+"); if(foutput != NULL) { for(c=0;c<total;c++) { fscanf(finput,"%d",&temp); fprintf(foutput,"%d\n",temp); sum = sum + temp; } } else printf("Error 03:Couldn't open output.txt in writing phase."); } else printf("Error 02:Couldn't open input.txt in reading phase."); avg=sum/(float)total; printf("The average of the numbers' is %0.2f\n",avg); fprintf(foutput,"The %d numbers' average is %f\n",total,avg); fclose(finput); fclose(foutput); } 大家讨论讨论吧 好的不好的都说一说 话说hw8的流程图扯到sort bubble的部份我就喇塞过去了... 实在不想想...反正code部份是交给下星期的我去处理... 大家讨论讨论hw7的吧 hw8没事也可以聊聊 这个版有一部份就是要这样用的 -- ......ID...... ......I am a learning Dancer......
