Summary:In this programming tutorial, we will learn different ways to convert a string into a char array in C++. Method 1: Using ‘for loop’ #include<iostream>usingnamespacestd;intmain(){stringstr;cout<<"Enter a string \n";getline(cin,str);//Create an empty char array of the same ...
1. The c_str() and strcpy() function in C++ C++ c_str() function along with C++ String strcpy() function can be used to convert a string to char array easily. The c_str() method represents the sequence of characters in an array of string followed by a null character (‘\0’). ...
C++ String to Char Array To convert a string to character array in C++, you can directly assign the string to character array, or iterate over the characters of string and assign the characters to the char array, or use strcpy() and c_str() functions. We shall go through each of these...

运行convert.c后输出如下: ch = C, i = 67, fl = 67.00ch = D, i = 203, fl = 339.00Now ch = SNow ch = P 1. 在我们的系统中,char是8位,int是32位。程序的分析如下。 -第9行和第10行:字符'C'被作为1字节的ASCII值存储在ch中。整数变量i接受由'C'转换的整数,即按4字节存储67。最后,fl...
