Check my code please

#1

I have written a code for calculating max freq character of the string

///my Code

#include
using namespace std;
int maxfreq(string str)
{

int n=str.length();
int i=0;
int j=i+1;
int c;
int m=0;
char Max='\0';
while(i!=n-1)
{
    while(j!=n-1)
    {
        int c=0;
        if(str[i]==str[j])
        {
            c++;
            j++;
        }
        else
        {
            j++;
        }
    }
    if(c>m)
    {
        m=c;

    if(m>Max){
        Max=str[i];

    }
    }
    i++;
}
return Max;

}

int main()
{
string str;
cin>>str;
char ch=maxfreq(str);
cout<<ch;
}

/// My code works fine on code blocks but while submitting the test cases are showing wrong . can you help me.

hi @Souryaman this approach is not good as it will take too much time. You can solve this problem in O(n) by using a frequency array.
