1. Implementation Algorithm specific

   • input validation
     • it prevents impropelrly formed data from entering an info sys
   • runniung total with loop
     • a lot of programs need to calcuate a running total to find the sum of a list of numbers or to calculate
   • Traversing a 1D - array
     • a lot of programs need to pass through each element of an array in turn, from the first element to the last element while performing some processing on each element

2. evaluation

   • fit for purpose
     • is when it fit to do its purpose
   • Efficient coding
   • robustness
   • readability
     • readable code

3. Testing

   • test data
   • errors
     • syntax error
       • are identified and reported by translator program when the program is translated
     • logic error
       • these are error in the logic of the code itself: for exemple, writing code to add two num instead of muti them, or sub two number the wrong way round
     • errors are classified into three different types: syntax,execution and logic errors

4. implementation computational constructs

   • concate strings
   • arithmetic operations
   • assign values
   • constructs for simple statements
   • complex conditions
   • logical operators
   • iteration and repetition
   • pre-defined functions
     • length
     • random
     • round
