将字符串转换为十六进制 ASCII 值
原文:https://www . geesforgeks . org/convert-a-string-to-十六进制-ascii-values/
给定一个字符串作为输入，编写一个程序将给定字符串的字符转换成十六进制等价 ASCII 值。 例:
Input : Geek
Output : 4765656b
Input : IronMan part 3
Output : 49726f6e4d616e20706172742033
ASCII 代表美国信息交换标准代码。ASCII 是一种标准，在 8 位代码的 256 个可用槽中分配字母、数字和其他字符。例如，小写“h”字符(Char)的十进制值为 104，二进制为“01101000”，十六进制为“68”。 ASCII 表 十六进制或简称为“十六进制”的编号系统使用 16 的基数系统。十六进制数使用 16 个符号{0，1，2，4，5，6，7，8，9，A，B，C，D，E，F}来表示所有的数字。这里，(A，B，C，D，E，F)代表(10，11，12，13，14，15)。
算法:
- 将最终十六进制字符串初始化为空。
- 考虑输入的每个字符，将其转换为整数。该整数值是该字符的 ascii 值。
- 将该整数值更改为十六进制值，并将该十六进制值添加到最终的十六进制字符串中。
上述思路的基本实现:
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to convert ASCII
// string to Hexadecimal format string
import java.util.Scanner;
class ASCIItoHEX {
// function to convert ASCII to HEX
public static String ASCIItoHEX(String ascii)
{
// Initialize final String
String hex = "";
// Make a loop to iterate through
// every character of ascii string
for (int i = 0; i < ascii.length(); i++) {
// take a char from
// position i of string
char ch = ascii.charAt(i);
// cast char to integer and
// find its ascii value
int in = (int)ch;
// change this ascii value
// integer to hexadecimal value
String part = Integer.toHexString(in);
// add this hexadecimal value
// to final string.
hex += part;
}
// return the final string hex
return hex;
}
// Driver Function
public static void main(String arg[])
{
// print the Hex String
System.out.println(ASCIItoHEX("Geek"));
}
}
Python 3
# Python3 program to convert ASCII
# string to Hexadecimal format string
# function to convert ASCII to HEX
def ASCIItoHEX(ascii):
# Initialize final String
hexa = ""
# Make a loop to iterate through
# every character of ascii string
for i in range(len(ascii)):
# take a char from
# position i of string
ch = ascii[i]
# cast char to integer and
# find its ascii value
in1 = ord(ch)
# change this ascii value
# integer to hexadecimal value
part = hex(in1).lstrip("0x").rstrip("L")
# add this hexadecimal value
# to final string.
hexa += part
# return the final string hex
return hexa
# Driver Function
if __name__ == '__main__':
# print the Hex String
print(ASCIItoHEX("Geek"))
