num to char

Recently wrote a program to find such a problem#include #includestring.h>using namespacestd;voidReverseChar*str) { intlen=strlen (str); Char*p=str; Char*q=str+len-1; while(pq) {Chartemp=*p; *p=*Q; *q=temp; P++; Q--; }}intMain () {Char*n1="123";

Programming has been a headache recently. This type of conversion can be done by knowing that it can be switched, but it is always hard to remember. I will keep searching through the Internet and summarize it here. For future convenience, of course,

Conversion between string, CString, char * Int to CString:CString. Format ("% d", int );...............................String to CStringCString. format ("% s", string. c_str ());C_str () is indeed better than data.....................................

The transformation between string,cstring,char* int Turn CString:Cstring.format ("%d", int);...............................String Turn CStringCstring.format ("%s", String.c_str ());Using C_str () is indeed better than data ()........................

Summarize the various types of Unicode conversions that have recently been used, and encounter additional additions in the future:1. String Turn CStringString a= "abc";CString str=cstring (A.c_str ());Or Str.format ("%s", A.c_str ())2, int turn

2014-03-02 20:14The following error occurred while compiling the following code:CPP: Error C2664: "int sprintf_s (char *,size_t,const char *,...)": cannot convert parameter 2 from "const char [3]" to "size_t"What does this mean, please? How do I

Unicode (unified code, universal code, Single Code) is a character encoding used on a computer. It sets a unified and unique binary code for each character in each language to meet the requirements of cross-language and cross-platform text

int turn CString:Cstring.format ("%d", int);...............................String Turn CStringCstring.format ("%s", String.c_str ());Using C_str () is really better than data ()........................................char* Turn CStringCstring.format

first, analyze the idea of the program :1: start with the first element of S, match the 1th element in T, and if equal, match the i+1 element of s with the 2nd element in T, and so on, if all elements of T match, then return position I; otherwise,

In the C + + standard library of functions. There are three functions that can convert the contents of a string into character arrays and c-string 1.data (), returns an array of strings without "" 2,C_STR (), returns an array of strings with "yes" 3,
