本程序统计字符数组c中小写字母(a～z)的个数，并将它们变成大写字母(已知字符a对应的ASCII比A对应的ASCII大32)。
public class exam_79{
public static void main(String[] args) {
char c[]={"a","D","W","f","q","P","i","o"};
______;
for(int i=0;i＜c.length;i++){
if(c[i]＞="a"&&c[i]＜="z"){
c[i]=______(c[i]-32);
______;
}
}
System.out.println("sum="+sum);
System.out.println(c);
}
}
