Problem Descriptions: The purpose of this assignment is to reinforce the lecture material on variable definition fusage and DU path. For each of the source code fragments below: 1) Construct a table listing all the line numbers where a variable is defined or used. You must list all the variables in each source code fragment. 2) Construct a DU Path table showing all paths from any definition to usage of every variable. A sample is given below: 1. Int aain() f 2. ehar operator: 3. I double firsthunber, secondilumber; 4. printf("Enten an operator (+,+,+)=") 6. printf("Enter two operands: ") ; 8. If (operator ==∗∗ ) ↑ 9. pelntf ( '  .11f+X.11f=X.11f′′, firstikumber, secondNumber, firsthumber + seconakiaber ) : 10. Yelse if (operator = "." ∗ ) \{ 11. peintf (−Z.11f−Z.11f=x.11fn, firstNunber, secondkumber, firsthunber − seconavumber ); 12. else if (operator =w∗.) \{ 13. printf( " x.11f⋅x.11f=x.11f′′, firstiumber, secondkumber, firsthumber - seconakunber); 14. ) else if (operator =η∗f∗) : 25. peintf (−x.11f/x.11f=8.11f∗, firsthunber, secondumber, firstkumber / seconavunber ); 16. ) else f 17. printf("Errorl aperator is not correct"); 18. ) 19. return 9 ; 2e. 3 DEF-USE Table:
