Write the function ft_calculator_fct that will take two integers and a character as arguments

The function must return the result of the operation performed on two integers

The operation will depend on the character argument:

• If the character is "+", add the first integer to the second (a + b)
• If the character is "-", substract the second integer from the first (a - b)
• If the character is "*", multiply the first integer by the second (a * b)
• If the character is "/", divide the first integer by the second (a / b)
• If the character is "%", return the rest of the division a / b
• If the character is different from those mentionned above, return 0

int ft_calculator_fct(int a, char operation, int b);

You have already wrote this function. The only new condition is that there must be a subfunction for every operation

• Addition / substraction / multiplication / division / modulo and error

The main function must use the return values of these subfunctions to return its own value. No operation can be performed in ft_calculator_fct itself

Examples:

ft_calculator_fct(3, '+', 2); //returns 5
ft_calculator_fct(3, '-', 2); //returns 1
ft_calculator_fct(9, '*', 5); //returns 45
ft_calculator_fct(9, '/', 5); //returns 1
ft_calculator_fct(9, '%', 5); //returns 4
ft_calculator_fct(9, 'a', 5); //returns 0
