Logic:
1. declare and Initialize the array
2. lets assume first number in the array is the biggest number and initialize value to max variable
3. Use loop to iterate from 1st element to end of array element and check if the array element value is greater than max variable value then store the maximum value in max variable.
4. Display max value.
************************
Output:
enter elements for array: 5 4 7 1 2
maximum no= 7
