### **C语言 整数与字符串的相互转换** ###

一、简述

C语言中整数与字符串的相互转换，有广泛应用的拓展函数(非标准库)，也可以自己尝试简单的实现。

二、整数转字符串

1、拓展函数itoa

itoa (表示 integer to alphanumeric)是把整型数转换成字符串的一个函数。

windows环境下，在<stdlib.h>头文件中有

char* itoa(int value,char*string,int radix);//value: 要转换的整数，string: 转换后的字符串,radix: 转换进制数，如2,8,10,16 进制等。

函数源码：

char* itoa(int num,char* str,int radix)
    {
    	char index[]="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";//索引表
    	unsigned unum;//存放要转换的整数的绝对值,转换的整数可能是负数
    	int i=0,j,k;//i用来指示设置字符串相应位，转换之后i其实就是字符串的长度；转换后顺序是逆序的，有正负的情况，k用来指示调整顺序的开始位置;j用来指示调整顺序时的交换。
    
    	//获取要转换的整数的绝对值
    	if(radix==10&&num<0)//要转换成十进制数并且是负数
    	{
    		unum=(unsigned)-num;//将num的绝对值赋给unum
    		str[i++]='-';//在字符串最前面设置为'-'号，并且索引加1
    	}
    	else unum=(unsigned)num;//若是num为正，直接赋值给unum
    
    	//转换部分，注意转换后是逆序的
    	do
    	{
    		str[i++]=index[unum%(unsigned)radix];//取unum的最后一位，并设置为str对应位，指示索引加1
    		unum/=radix;//unum去掉最后一位
    
    	}while(unum);//直至unum为0退出循环
    
    	str[i]='\0';//在字符串最后添加'\0'字符，c语言字符串以'\0'结束。
    
    	//将顺序调整过来
    	if(str[0]=='-') k=1;//如果是负数，符号不用调整，从符号后面开始调整
    	else k=0;//不是负数，全部都要调整
    
    	char temp;//临时变量，交换两个值时用到
    	for(j=k;j<=(i-1)/2;j++)//头尾一一对称交换，i其实就是字符串的长度，索引最大值比长度少1
    	{
    		temp=str[j];//头部赋值给临时变量
    		str[j]=str[i-1+k-j];//尾部赋值给头部
    		str[i-1+k-j]=temp;//将临时变量的值(其实就是之前的头部值)赋给尾部
    	}
    
    	return str;//返回转换后的字符串
    }

示例程序：

#include <stdlib.h>
    #include <stdio.h>
    int main()
    {
    	int number1 = 123456;
    	int number2 = -123456;
    	char string[16] = {0};
    	itoa(number1,string,10);
    	printf("数字：%d 转换后的字符串为：%s\n",number1,string);
    	itoa(number2,string,10);
    	printf("数字：%d 转换后的字符串为：%s\n",number2,string);
    	return 0;
    }

2、自己简单实现

实现代码

#include <stdio.h>
    
    char* Int2String(int num,char *str);//函数声明 
    int main()
    {
    	int number1 = 123456;
    	int number2 = -123456;
    	char string[16] = {0};
    	Int2String(number1,string);
    	printf("数字：%d 转换后的字符串为：%s\n",number1,string);
    	Int2String(number2,string);
    	printf("数字：%d 转换后的字符串为：%s\n",number2,string);
    	return 0;
    }
    
    char* Int2String(int num,char *str)//10进制 
    {
    	int i = 0;//指示填充str 
    	if(num<0)//如果num为负数，将num变正 
    	{
    		num = -num;
    		str[i++] = '-';
    	} 
    	//转换 
    	do
    	{
    		str[i++] = num%10+48;//取num最低位 字符0~9的ASCII码是48~57；简单来说数字0+48=48，ASCII码对应字符'0' 
    		num /= 10;//去掉最低位	
    	}while(num);//num不为0继续循环
    	
    	str[i] = '\0';
    	
    	//确定开始调整的位置 
    	int j = 0;
    	if(str[0]=='-')//如果有负号，负号不用调整 
    	{
    		j = 1;//从第二位开始调整 
    		++i;//由于有负号，所以交换的对称轴也要后移1位 
    	}
    	//对称交换 
    	for(;j<i/2;j++)
    	{
    		//对称交换两端的值 其实就是省下中间变量交换a+b的值：a=a+b;b=a-b;a=a-b; 
    		str[j] = str[j] + str[i-1-j];
    		str[i-1-j] = str[j] - str[i-1-j];
    		str[j] = str[j] - str[i-1-j];
    	} 
    	
    	return str;//返回转换后的值 
    }

三、字符串转整数

1、拓展函数  
            atoi (表示 alphanumeric to integer)是把字符串转换成整型数的一个函数。  
            windows环境下，在<stdlib.h>头文件中

int  atoi(const char *nptr);//字符串转整数函数，nptr: 要转换的字符串

源码：

int  atoi(const char *nptr)
    {
            return (int)atol(nptr);
    }
     
    long  atol(const char *nptr)
    {
            int c;              /* 当前要转换的字符(一个一个字符转换成数字) */
            long total;         /* 当前转换结果 */
            int sign;           /* 标志转换结果是否带负号*/
     
            /*跳过空格，空格不进行转换*/
            while ( isspace((int)(unsigned char)*nptr) )
                ++nptr;
     
            c = (int)(unsigned char)*nptr++;//获取一个字符准备转换 
            sign = c;           /*保存符号标示*/
            if (c == '-' || c == '+')
                c = (int)(unsigned char)*nptr++;    /*跳过'+'、'-'号，不进行转换*/
     
            total = 0;//设置转换结果为0 
     
            while (isdigit(c)) {//如果字符是数字 
                total = 10 * total + (c - '0');     /* 根据ASCII码将字符转换为对应的数字，并且乘10累积到结果 */
                c = (int)(unsigned char)*nptr++;    /* 取下一个字符 */
            }
     
     		//根据符号指示返回是否带负号的结果 
            if (sign == '-')
                return -total;
            else
                return total;  
    }

示例程序：

#include<stdio.h>
    #include<stdlib.h> 
    
    int main()
    {
    	printf("字符串\"123456\"转换为数字：%d\n",atoi("123456"));
    	printf("字符串\"-123456\"转换为数字：%d\n",atoi("-123456"));
    	return 0;
    }

2、自己简单实现

实现源码

#include<stdio.h>
    
    int String2Int(char *str);//函数声明 
    int main()
    {
    	printf("字符串\"123456\"转换为数字：%d\n",String2Int("123456"));
    	printf("字符串\"-123456\"转换为数字：%d\n",String2Int("-123456"));
    	return 0;
    }
    
    int String2Int(char *str)//字符串转数字 
    {
    	char flag = '+';//指示结果是否带符号 
    	long res = 0;
    	
    	if(*str=='-')//字符串带负号 
    	{
    		++str;//指向下一个字符 
    		flag = '-';//将标志设为负号 
    	} 
    	//逐个字符转换，并累加到结果res 
    	while(*str>=48 && *str<57)//如果是数字才进行转换，数字0~9的ASCII码：48~57 
    	{
    		res = 10*res+  *str++-48;//字符'0'的ASCII码为48,48-48=0刚好转化为数字0 
    	} 
    
        if(flag == '-')//处理是负数的情况
    	{
    		res = -res;
    	}
    
    	return (int)res;
    }

    	printf("字符串\"-123456\"转换为数字：%d\n",String2Int("-123456"));
    	return 0;
    }
    
    int String2Int(char *str)//字符串转数字 
    {
    	char flag = '+';//指示结果是否带符号 
    	long res = 0;
    	
    	if(*str=='-')//字符串带负号 
    	{
    		++str;//指向下一个字符 
    		flag = '-';//将标志设为负号 
    	} 
    	
    	sscanf(str, "%ld", &res);
    	if(flag == '-')
    	{
    		res = -res;
    	}
    	return (int)res;
    }

 <tbody> 
  <tr> 
   <th style="background-color:#f4f4f4;vertical-align:top;">ASCII值</th> 
   <th style="vertical-align:top;">控制字符</th>
