Set Threshold

Question

Problem: Set Threshold. Solve this hands-on electronics task on EWskills.

Accepted Answer

#include 
using namespace std;

void setThreshold(int x) {
    cout << "Threshold set to " << x;
}

void setThreshold(double x) {
    cout << "Threshold set to " << x;
}

int main() {
    double val;
    cin >> val;

    if (val == (int)val) {
        setThreshold((int)val); // integer overload
    } else {
        setThreshold(val);      // double overload
    }

    return 0;
}

Solution Details

Two functions with the same name setThreshold but different parameter types (int and double).
The compiler decides which function to use based on the type of argument.
main() handles whether the value is whole (int) or decimal (double).

👉 In simple words:
You only write the two versions of setThreshold. The program chooses which one to call depending on whether the input has decimals.

Significance for Embedded Developers

Thresholds can be set in raw counts (e.g., ADC = 1023) or in real units (e.g., volts = 3.75).
Function overloading allows both cases to be handled naturally, without creating separate function names.
