二級C程序脩改（四）

= = = = = = = = = = = = = = = = = = = = = = = = = = = = =
測試描述:
= = = = = = = = = = = = =
例如，儅數組A中的值爲:1，3，5，7，8
而數組B中的值爲:2，3，4，5，8
調用此函數後，C中存儲的數據爲:-7，-2，1，4，6。
main函數和其他函數不要做任何改動，衹要在fun函數的花括號裡填一些你寫過的語句就可以了
。
= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
程序:
= = = =

}

main()
{ int i，a[100]={1，3，5，7，8}，b[100]={2，3，4，5，8}，c[100]；
clrscr()；
fun(a，b，c，5)；
printf("結果是:")；
for(I = 0；iprintf(" \ n")；
NONO()；
}

O ()
{
FILE *rf，* wf
int a[100]，b[100]，c[100]，I，j；
rf = fopen("in.dat"，" r")；
wf = fopen("bc02.dat"，" w")；
for(I = 0；I < 5；I){
for(j = 0；j < 5；j ) fscanf(rf，" %d，"，& a[j])；
for(j = 0；j < 5；j ) fscanf(rf，" %d，"，& b[j])；
fun(a，b，c，5)；
for(j = 0；j < 5；j ) fprintf(wf，" %d"，c[j])；
fprintf(wf，" \ n")；
}
f close(RF)；
fclose(wf)；
}
