C Programming

Calculator In this task, you will learn how to use conditional statements and formatted input and output using scant and printf. You are required to implement simple_math function that fulfills the following requirements. 1. The function is declared in source.h as void simple_math(void); 2. Implement the function definition in source.c. 3. The function should expect the user input in the form where is a float type floating-point number. is one of '+','','*' or '7' characters corresponding to the basic mathematical operators. is the space character. 4. If the user entry is not in the expected format, the function should print ERR 5. If the user enters any other operator than the above stated ones, the function should print ERR 6. If the user enters the required input, the function performs the stated operation on the stated numbers and prints the result with a precision of a single decimal. An example call of the function is shown below. The input from the user is highlighted. 8 - 2 6. 55 25.6 8.3 / 5.1 1.6 2.2 / ERR -3.456 - 2.31 -5.8 2.45 : 1.0 ERR + 2.0 ERR
