Here's a practical, minimal guide for using GDB in Ubuntu terminal — from launching to setting breakpoints and navigating your code. 🧰 Step 1: Compile with Debug Symbols Use -g and disable optimizations ( -O0 preferred for debugging): bash Copy Edit g++ -g -O0 -o myprog myprog.cpp 🚀 Step 2: Launch GDB bash Copy Edit gdb ./myprog You'll see a (gdb) prompt. 🎯 Step 3: Set Breakpoints You can set breakpoints in three main ways : ✅ a. At a function gdb Copy Edit (gdb) break main ✅ b. At a specific file and line gdb Copy Edit (gdb) break myprog.cpp:42 ✅ c. At a method in a class gdb Copy Edit (gdb) break MyClass::doSomething If the symbol is mangled (C++), GDB usually demangles automatically, especially if compiled with -g . ▶️ Step 4: Run the Program gdb Copy Edit (gdb) run 🧠Step 5: Navigate Command Meaning next or n Step over current line step or s Step into function call finish Run until current function returns continue or c Continue until...
Take a list of items that will run in inverter like 2fans, 1 LED tubelight, 1 laptop, 2 LED TV, etc Now calcullate sum of their power e.g 2*60+1*20+100+2*100 WH=440 WH Now add 25% to above power sum e.g 440*125%=550WH Then multiply it by power factor (most case it's 1/0.8) e.g 550/.08=687.5 WH For every inverter has its own effeiency say 90%,80%, etc Therefore, inverter power that has to be purchased = 687.5/90%=763.888 VA Above is how to calculate inverter power that has to be purchased. ---- Now comes how to choose battery power Batter power (VA) = Home Load * Backup (hrs)/Battery Vold = 687.5WH*2hr/12amp = 114.58 --- This is how you do calculations for purchasing invertor ========================= Bibliography
