Pretty close with the last effort, but you still need to work on whether you're programming in C or C++. [code] #include <stdio.h> #include <math.h> int main() { /*!! missing */ char buff[BUFSIZ]; int i, a, b, c, x, n; printf("Enter the value for n:"); /*!! not scanf */ /*!! …

Apart from using void main (this is wrong), what's your question?

Seems to me like it's a variation of the knapsack problem. [url]http://en.wikipedia.org/wiki/Knapsack_problem[/url] One way would be - all permutations of 1 coin - all permutations of 2 coins - all permutations of 3 coins etc For each permutation, add them up and see if they match the total you want.

A few instant problems 1. Over reliance on global variables. 2. Your print routine starts at 'p', not first.

The string returned by getline probably has a newline on the end of it (which won't be in any string you're comparing against). Or it's the classic mixing "cin >> var" with getline, and getline just returns with the newline which cin left behind.
