c#成績統計(switch語句)

{int a[5]={0},b[10]={100,95,85,75,65,55,15,0,72,66},i;

clrscr();

for(i=0;i<=9;i++)

{ switch(b[i]/10)

{ case 10: ;

case 9: a[0]++;break; case 8: a[1]++;break;

case 7: a[2]++;break; case 6: a[3]++;break;

default: a[4]++; } }

for(i=0;i<=4;i++)printf("%d,",a[i]);

}========================這壹個是隨機生成測試數據的 random可以用scanf代替掉，可以不用數組#include <stdlib.h>

main()

{int a[5]={0},scores,i;

clrscr();

for(i=0;i<=9;i++)

{

scores=random(101);

printf("%d\t",scores);

switch(scores/10)

{

case 10: ; case 9: a[0]++;break;

case 8: a[1]++;break; case 7: a[2]++;break;

case 6: a[3]++;break; default: a[4]++;

}

}

printf("\n");

for(i=0;i<=4;i++)printf("%d,",a[i]);

}
