how i prepare for technical interview for tcs because i am from ece branch i have not more knowledge about c/c++ language

In technical interview they will ask question about programming language. You can't be 100% sure if You are good at C and C++.
You must be perfect in programming language like C,C++,JAVA,.Net,SQL,Data Structure.
But your chances are good if you are perfect in C and C++ but they can ask you of Java , .Net etc
Actually nowadays companies want candidate which are good at programming language so that they don't have to make efforts to teach that candidate programming languages.
It will be better if you learn C and C++ from any institute.
Practice well and then go for interview.
