In this we concatenate two different string without using concatenation functionstrcat(). Example #include <string.h>#include <iostream>usingnamespacestd;intmain() {// declare stringscharstr1[100];charstr2[100];// input first stringcout<<"Enter first string : "<<endl; cin.getline(str1,100...
std::string concatenateWithSprintf(const std::string& str, int num) { char buffer[100]; std::sprintf(buffer, "%s%d", str.c_str(), num); return std::string(buffer); } int main() { std::string result = concatenateWithSprintf("Age: ", 30); std::cout << result << std::endl;...
You can also specify the starting character of a string and number of characters you want to copy to the array. string str1 = "ppp"; char[] chrs = new Char[2]; str1.CopyTo(0, chrs, 0, 2); The Clone method returns a new copy of a string in form of object. The ...

char *p = malloc(s * (an + bn)); // Copy elements from first array to concatenated array memcpy(p, a, an * s); // Copy elements from second array to concatenated array after the first array's elements memcpy(p + an * s, b, bn * s); // Return pointer to the concatenated ...
you can just add it in, but if the array that char * points too isn't large enough, then you'll have to declare a new one... what code do you currently have? - edit: when I say add it in, I mean, find where on the array to put it and put it there ...
C/C++ : converting std::string to const char* I get the error : left of '.c_str' must have class/struct/union type is 'char *' C# to C++ dll - how to pass strings as In/Out parameters to unmanaged functions that expect a string (LPSTR) as a function parameter. C++ int to ...

You have to allocate some memory, then copy one and append the other. 1 2 3 char*s =new[strlen(word)+strlen(word2)+1]; strcpy(s,word); strcat(s,word2); Or just use std::string in C++. Mar 15, 2020 at 1:54am closed account (Ey80oG1T) ...
In one formula, you can concatenate up to 255 strings, a total of 8,192 characters. The result of the CONCATENATE function is always a text string, even when all of the source values are numbers. Unlike the CONCAT function, Excel CONCATENATE does not recognize arrays. Each cell reference ...
