Hi,

//implementation of charCnt

int charCnt(string filename,char ch){

ifstream inputfile(filename);

char inChars;

int count=0;

if(!inputfile.is_open()){

cout<<"Error opening "<<filename<<endl;

exit(1);

}else{

//reading from the input file character by character

//There is no need to use getc function you can use the >> parameters to read from a ifstream that is very easy

while(inputfile>>inChars){

if (inChars==ch){

count++;

}

}

}

return count;

}

Please copy and paste the above funtion and try to run your code with a valid filename
