🔨 Compiling and Running Programs

C++ Programs

Basic Compilation

# Simple compile
g++ filename.cpp -o outputname

# Run
./outputname

With Debugging Information

g++ -g filename.cpp -o outputname

With Optimization

g++ -O2 filename.cpp -o outputname

With C++11/14/17 Standard

g++ -std=c++11 filename.cpp -o outputname
g++ -std=c++17 filename.cpp -o outputname

Multiple Files

g++ file1.cpp file2.cpp -o outputname

Java Programs

Basic Compilation and Execution

# Compile
javac ClassName.java

# Run
java ClassName

With Package Structure

# Compile with package
javac -d . PackageName/ClassName.java

# Run with package
java PackageName.ClassName

Multiple Files

# Compile all java files in directory
javac *.java

# Or specific files
javac File1.java File2.java

❗ Common Issues

C++ Issues

Issue: "g++ command not found"

  • Solution: Install g++ compiler or add to PATH

Issue: "undefined reference to..."

  • Solution: Link all necessary files during compilation

Issue: Header file not found

  • Solution: Ensure header files are in the same directory or use -I flag

Java Issues

Issue: "javac/java command not found"

  • Solution: Install JDK and add to PATH

Issue: "Could not find or load main class"

  • Solution: Ensure class name matches filename, check CLASSPATH

Issue: "UnsupportedClassVersionError"

  • Solution: Ensure JDK and JRE versions match
