Write a main program for the MIPS machine that implements a simple five-function calculator and prompts the user to enter a pair of decimal integers (A and B) followed by a character that specifies one of the operators:

+ for addition to compute A+B

- for subtraction to compute A-B

* for multiplication to produce the 32-bit product A*B

/ for division to produce the 32-bit integer quotient A/B.

% for the modulo function (i.e. the remainder produced when A is divided by B)

Your program should display the result produced by performing the indicated operation on the two input operands A and B. Only the five operators listed above should be allowed and an attempt to divide by zero should be prohibited.

A sample execution of the program is shown below:

Your main program should prompt the user for input operands and the operator. Use the READ_CHAR syscall to obtain the operator and use READ_INT syscalls to obtain the operands.

Define a separate function for each of the allowed operators and use the function names ADD, SUB, MUL, DIV and MOD. Each function should accept the two operands in $a0 and $a1, and accept the character representing the operator in $a3. Each function should return the appropriate result (the sum, the difference, the product, the quotient, etc.) in register $v0. You need not be concerned with overflow, just use the 32-bit result in each case.

Upon return from the function, the main program should display the result on the console as shown in the sample output above

('y' or "I'): y Enter the first decinal integer operand 26 Enter the second decinal integer operand: 30 Enter the operator or- he resul4 Continue?
