Hi I am trying to use fork() system command which requires unistd.h. When I try to include that file, it give me following error:fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory Error executing cl.exe....
because I must always place it as last include.So I don't make it inline by declaring in a ...
In the following code, no delimiter ("") is specified to print the string in its original form. Example Code: #include <iostream> #include <iterator> #include <string> #include <vector> using std::cin; using std::copy; using std::cout; using std::endl; using std::string; using ...
cout << "0x" << hex << (unsigned short)((unsigne d char) *iter) << " "; } The *iter is char, not unsigned char. So, I have to use double casting to do the job. If I use c-style function, I can easily specify "%x" in the format string of printf() to print the char...

In this example, we can use a function to print the elements of an array: #include<iostream> voidfunction(intarr[],intsize); intmain() { intarray[] = {1,2,3,4,5}; function(array,5); for(inti =0; i <5; i++) { std::cout << array[i] << std::endl; ...
NOTE: if you are printing value of std::string instead of C-String (char array) you will have to use the value from <string object>.data(), or <string object>.c_str(). Example: #include <string> #include <cstdio> int main() { std::string sol {"SoloLearn"}; const char *com...
The fast way to convert is to usetransformalgorithm associated tolowerandupperfunction. #include<algorithm>#include<string>#include<iostream>usingnamespacestd;intmain(){stringdata="ABc1#@23yMz";transform(data.begin(),data.end(),data.begin(),(int(*)(int))toupper);cout<<data<<endl;transf...
#include<bits/stdc++.h>usingnamespacestd;voidsolve(){intn;cin>>n;for(inti=1;i<=n;i++){if(n%i==0){cout<<i<<" ";}}cout<<endl;}intmain(){intt;cin>>t;while(t--){solve();}return0;} I'll discuss in another editorial how to optimize the algorithm to find divisor...
