Question

Make a program in C that takes in four parameters,
1) string of +,- or * for addition,subtraction, or multiplication
2) 32 bit two's complement integers where a 'b' in front of it means binary, 'o' means octal 'd' means decimal, and 'x' means hexadecimal
3) another 32 bit two's complement number with the same base as the first number, so if first number was a binary the second would also be a binary
4) the type of base you want the output to be in, could be binary, hexadecimal, octal, or decimal
Example runs on terminal
