C#程序计算给定字符串中的大小写字符
要计算字符串中的大写字符，请检查以下条件-
myStr[i]>='A' && myStr[i]<='Z'
要计算字符串中的小写字符，请检查以下条件-
myStr[i]>='a' && myStr[i]<='z'
示例
您可以尝试运行以下代码来计算给定字符串中的大小写字符。
using System;
public class Demo {
public static void Main() {
string myStr;
int i, len, lower_case, upper_case;
myStr = "Hello";
Console.Write("String: "+myStr);
lower_case = 0;
upper_case = 0;
len = myStr.Length;
for(i=0; i<len; i++) {
if(myStr[i]>='a' && myStr[i]<='z') {
lower_case++;
} else if(myStr[i]>='A' && myStr[i]<='Z') {
upper_case++;
}
}
Console.Write("\nCharacters in lowecase: {0}\n", lower_case);
Console.Write("Characters in uppercase: {0}\n\n", upper_case);
}
}输出结果
String: Hello Characters in lowecase: 4 Characters in uppercase: 1
