3、分別顯示出“ThisisYES.”與“ThisisNO.”。請?zhí)羁铡?includevoidYesNo(charch){switch(ch){case’y’:case’Y’:printf(“ThisisYES.”);break;case’n’:case’N’:printf(“ThisisNO.”)}}main(){charch;printf(“Enterachar‘y’,’Y’,or’n’,’N’);ch=___________________;printf(“ch:%c”,ch);YesNo(ch);}5.
4、以下Check函數(shù)的功能是對value中的值進行四舍五入計算，若計算后的值與ponse值相等，則顯示“WELLDONE??！”，否則顯示計算后的值。已有函數(shù)調(diào)用語句Check（ponse,value）；請?zhí)羁?。VoidCheck(intponse,floatvalue){intval;val=_______________________________;printf(“計算后的值：%d”,val);if(_____________________)printf(“WELLDONE!!!”);elseprintf(“Sorrytheco
