Line by line c - c++ code debugging in Linux ubuntu

c, c++, debugging

Solution

gdb (The Gnu debugger) is best choice

apt-get install gdb

man gdb

1.    cc -g file.c             //       compile your program ,this will generate a.out file with required debugging information 

2.    gdb a.out                //        start with gdb

3.    b main                   //        to set break point at main       

4.     run                     //        run now , and it will stop at break point main 

5.     s                       //        option s is to step single line and even step into functions

6.     n                       //        option n is to execute next line and step over functions  

7.     p    variable name      //        to print the value of variable at that particular instance very helpful

Problem
