initialize, and use in our code. Related to such issues, answer the following:
1. Pick any TWO of the following concepts and only explain the relation between them VERY
BRIEFLY: => [span, live time, scope, principle of proximity]
2. For all the variables used in the code snippet below, you are required to find and provide:
a. average span for each variable (separate for each variable)
b. Average live time for the complete code (single value)

void SummarizeData() {
int numNewData = 0;
int newData = 0;
int totalOldData = 0;
int totalNewData=10;
int oldData = 0;
String numOldData = null;
GetOldData( oldData, numOldData );
GetNewData( newData, numNewData );
totalOldData = Sum( oldData, numOldData );
totalNewData = Sum( newData, numOldData );
PrintOldDataSummary( oldData, totalOldData, numOldData );
PrintNewDataSummary( newData, totalNewData, numNewData );
SaveOldDataSummary( totalOldData, numOldData );
