Before reading this problem please note that this is a PRACTICE problem for hp codewars (a programming competition), I am not asking the forum about a real problem. My program is supposed to take the following input:
- A number that represent the number of candies in a jar
- The number of guesses that the user will be entering in
- A person's name, followed by a space and then their guess
example:
- 422: Amount of candies in jar
- 2: Number of guesses
- Joe 324: Name of guesser and their guess of how many candies are in the jar
- Mary 435: Second guesser and guess
The output should be the name of the person who had the closest guess
example:
- Mary
I am currently coding the function that returns the closest number to the guess. However when I run the code, it gives me the error no match for call '(std::vector<int>) (int) on two lines. The lines that are sending back errors are pointed out in comments in my code.
Here is my code:
vector<int> compare(vector<int> nums, int loopnum, int ans){
vector<int> buff2;
for (int i = 0; i<loopnum;i++){
vector<int>diff;
int buff = ans - nums.at(i);
for (int j = 0; j<loopnum; j++){
diff.push_back(buff);
for (int k = 0; k<diff.size(); k++){
if (k == 0){
buff2.push_back(diff.at(k));
}
else{
// this line is sending back an error
if ((abs(buff2(0))) > abs(diff.at(k))) {
buff2.clear();
buff2.push_back(diff.at(k));
}
// this line is also sending back an error
else if ((abs(buff2(0))) == abs(diff.at(k))){
buff2.push_back(diff.at(k));
}
}
}
}
}
return buff2;
}
Please help me fix this!
