If 99% of the program is written in FORTRAN and the remaining 1% in assembly language, the percentage increase in the programming time compared to writing the entire program in FORTRAN and rewriting the 1% in assembly language is

If the entire program is written in FORTRAN, the percentage increase in the execution time, compared to writing the entire program in FORTRAN and rewriting the 1% in assembly language is

If 99% of the program is written in FORTRAN, and the remaining 1% in assembly language the percentage increase in the execution time, compared to writing the entire program in FORTRAN and rewriting the 1% in assembly language is

If a weightage of 3 is given to the programmers effort and a weightage of 2 is given to the execution time, then coding 99% in FORTRAN and the 1% in assembly language performs better than coding in FORTRAN completely and rewriting the 1% in assembly language by a factor of about

Data structure suitable for the application is discussed in

Design phase will usually be

Assertion are conditions which are true at the point of execution

Assuming the existence of a start and end nodes for a program graph, the total number of paths is equivalent to the ….. set of test data required to test the software.

Let M be a node that represents a if-then-else node in a Program Graph. Let the number of paths from its if part to the end nody is y, and from the else part to the end node is z. If the number of paths from the start node to the node M is x, then the total number of paths through M is

If X is a case statement in a Program Graph with n cases instead of an if-then-else statement in the previous question with each case leading to only one path to end node, total number of paths through X is

Structured programming codes include
