Software testing:-  It is a program intended to find errors. It is a process to evaluate the functionality of a software application with an intent to find weather the developed software meet the specified required or not & to product is defect free in order to produce the quality product. Software testing principals:- Testing is a process which shows the presence of defect in the application. Exhaustive testing is impossible:-There is less possibility of testing with combinations of input, data, test & cinereous & recondition as they will take more time to test the process. Therefore the testing team can use some important testing criteria instead of doing exhausting testing. Testing activities will be conducted in the software or system development life cycle to find the defects as soon as possible. If errors are found in an initial stage of the development life cycle then it will be easier & cheaper to fixed the errors. Testing is context development . It approac...

 Q. Write a program in C++ to print pyramid  with star (*) ?        Ans:- #include<iostream.h> #include<conio.h> void main() { int i,j,k; clrscr(); for(i=1;i<=5;i++) { for(j=1;j<=5-1;j++) { cout<<" "; } for(k=1;k<i*2;k++) { cout<<"*"; } cout<<"\n"; } getch(); }

Software:-  Software is a define as a collection of programs documentation and operating procedures . The institute of electronic & electrical engineering (IEEE). We can say collection of computer programs procedures, rules & associate documentation data. It phases no mass , no value & n color which makes  it non-degradable, entity for a long period. 1. Software dose not wear out or get tired. 2. Software controls, integrates & massage the hardware components of a computer system. 3. It also instruct the computer what needs to we done to perform specific task & how it is to be          done.  Software characteristics:- Functionality:- Refers to the degree of performance of the software against its indeed purpose. Reliability:- Refers to the ability of the software to provide desire functionality under the given condition. Usability:- Refers to ability of software to use system resources in the most effective & efficient man...
