Calculator Application with LUC
The following code defines a simple calculator function, simple_calc, which performs basic arithmetic operations based on a given operator. The function supports addition and subtraction, returning the result of the operation or 0 if an invalid operator is provided.
function int simple_calc(string sign, int first, int second){
if sign == "+" {
r first + second;
}
else if(sign == "-") {
int result = first - second;
r result;
}
else {
return 0;
}
}
function Main(){
resPlus := simple_calc("+", 10, 20);
resPlusString := to_string(resPlus);
print(resPlus);
resMinus := simple_calc("-", 5, 2);
string resMinus = to_string(resMinus);
print(resMinus);
print("Done");
}
The simple_calc function takes three parameters: an operator (sign) as a string and two integers (first and second). It checks the operator and performs the corresponding calculation. If the operator is "+", it returns the sum of the two numbers. If it is "-", it calculates the difference and returns the result. Any other operator results in returning 0.
The Main function demonstrates the usage of simple_calc by performing an addition and a subtraction. The results are converted to strings and printed. Finally, the program prints "Done" to indicate completion.
