You can download the official (64-bit) setup from the SourceForge repository . While this version is a classic choice for beginners, it is no longer actively maintained. Installation Steps
64-bit code runs faster on modern CPUs for integer-heavy operations (e.g., cryptography, big number arithmetic, or large arrays). Always compile with -O2 -m64 for your submissions. dev-c 5.11 download 64 bit
It was a typical Tuesday morning for Alex, a computer science student. He had a project due soon and needed to write a C++ program to simulate a banking system. As he sat in front of his computer, he realized he didn't have a suitable Integrated Development Environment (IDE) installed. That's when he remembered Dev-C++, a free and popular IDE for C and C++ programming. You can download the official (64-bit) setup from
: Supports syntax highlighting, code completion, and a class browser to navigate code structures easily. Always compile with -O2 -m64 for your submissions
Choose your installation folder (default is usually fine) and click First Launch : Once finished, click
Your compiler is still 32-bit. Double-check the binary paths. Ensure that x86_64-w64-mingw32-gcc.exe exists in the bin folder.
