Who can help me? This is my homework

Two-Input Function Calculator Function Behavior ADD a b a + b SUB a b a - b MUL a b a * b MAX a b (a>=b) ? a : b MIN a b (a<b) ? a : b EX1, “ADD MUL 2 3 4” is 2*3+4 = 10 EX2, “ADD 4 MUL 3 3” is 4+3*3 = 13 EX3, “ADD MUL 2 3 MUL 4 5” is 2*3+4*5 = 26 Sample Input 5 /*this is show how many Two-Input Function*/ ADD 3 4 ADD MUL 3 4 SUB 2 3 ADD 4 MUL 2 3 MAX 1 MIN ADD 5 1 3 ADD 2 MAX ADD 2 3 MUL 2 3 Sample Output 7 11 10 3 8

We are not here to do your homework. If you have specific questions we can help, but nobody should do your homework for you.

input number of lines loop over each line until count above reached for each loop iteration : read line break into words (store words in an array) write a function that looks at the 1st array element, matching the correct command. check the next array entry - if number use it, otherwise recursively call yourself to decode another command. do the same for the 2nd arg, then call the appropriate operation with the 2 arguments based on the original value containing the command name. key point here is recursion. if you don't know what recursion is, look it up.
