Here I am going to present two methods that can be used for finding maximum among more that two numbers using max() and split a string around any delimiter.
Use max() for more than two numbers
max() is a c++ library function used to calculate maximum among it's arguments.
use
cout<<max(4,9);
// output : 9
To calculate max among more than two numbers, we usually do this.
// calculate max of 4, 8 and 45
cout<<max(max(4,8),45);
// 45
But, instead of complacting the code, we car write it like this
// calculate max of 4, 8 and 45
cout<<max({4,8,45});
// 45
split a string around any delimiter
Suppose you have a string str
string str = "This, is, rahul";
and you would like to remove the , from the string and return all the strings as an array of string
// should be
["this","is","rahul"];
We can solve this problem using some techniques
#include<bits/stdc++.h>
using namespace std;
const vector<string> split(const string& s, const char& c)
{
string buff{""};
vector<string> v;
for(auto n:s)
{
if(n != c) buff+=n; else
if(n == c && buff != "") { v.push_back(buff); buff = ""; }
}
if(buff != "") v.push_back(buff);
return v;
}
int main()
{
string str{"the quick brown fox jumps over the lazy dog"};
vector<string> v{split(str, ' ')};
for(auto n:v) cout << n << endl;
return 0;
}
The code speeks very well.
Let me know if this can be improved in any way.
