Question

C++

2) Functions with arrays

• Write a function that returns a count of how many temperatures are below freezing (32 degrees Fahrenheit). The function takes two parameters:

i) temps, an array of temperatures (in Fahrenheit degrees)

ii) numTemps, the number of temperatures

• Write a main() that initializes an array of temperatures (hard-coding the values is fine) and prints the number of temperatures below freezing. Your main() must call the above function to compute this result for output.

Answer 1

#include <iostream>

using namespace std;

int countFreezing(int temps[], int numTemps){
    int count = 0;
    for(int i = 0;i<numTemps;i++){
        if(temps[i]<32){
            count++;
        }
    }
    return count;
}

int main()
{
    int temps[] = {34,56,21,87,31,76,28,65};
    int numTemps = 8;
    cout<<countFreezing(temps,numTemps);

    return 0;
}
