Put simply, a solution to Change-Making problem aims to represent a value in fewest coins under a given coin system. This program was requested by one of readers on our Facebook Page. The program should output a way to represent the given amount using fewest number of coins. For example. if you have coins of value 1, 2, 5 and 10 and want to represent 26, the program should output the correct solution 10×2 5×1 2×0 1×1 the owed amount is less than the largest, we move to next largest coin, so on and so forth. Greedy approach works best with Canonical Coin systems and may not produce optimal results in arbitrary coin systems. For example, if denominations are {4, 3, 1}, number 6 is represented as 4×1 3×0 1×2 by this program; taking 3 coins. The correct answer in this case is. C PROGRAM FOR INFIX TO POSTFIX CONVERSION AND EVALUATION OF POSTFIX EXPRESSION. Infix to postfix conversion and postfix expression evaluation. In this C Program, we take an infix expression as input from the user and convert it in to a postfix expression using a stack. Then we evaluate that postfix expression to obtain the result. Write a C Program to convert a given infix expression to postfix and evaluate it. Infix expression is the most commonly used expression and we are all familiar with this. In Infix expression, the operator is between two operands, as in 1 + 2, or “5 + ((2 + 6) × 9) − 8”. The problem is divided into two tasks. First, the given infix expression is converted to a postfix expression. Then we take that
