If-Else Statement in C++

Image
  Introduction In real life, we take decisions every day. If it is raining, take an umbrella If marks are good, celebrate Else, study harder Similarly, in programming, we often need to make decisions . In C++, this decision-making is done using the if–else statement . The if–else statement allows a program to choose different paths of execution based on conditions. What is an If–Else Statement? An if–else statement checks a condition and executes code based on whether the condition is true or false . If the condition is true , the if block runs If the condition is false , the else block runs This helps the program behave intelligently instead of running the same code every time. Why Do We Need If–Else in C++? Without decision-making statements: Programs would run only in one direction No logical thinking would be possible Real-world problems cannot be solved Uses of if–else: Checking age eligibility Student grading system Login validation ...

Variables and Data Types in C++

Image
               📌 Variables in C++ 🔹 What is a Variable? A variable is a container used to store data in a program. 👉 Example (simple): int age = 20 ; int → data type age → variable name 20 → value 🔹 Why Variables are Needed? To store data To change data during program execution To perform calculations 👉 Example: int a = 5 ; int b = 10 ; int sum = a + b; 🔹 Rules for Naming Variables Must start with a letter or underscore (_) Cannot start with a number ❌ No spaces allowed Cannot use C++ keywords ✅ Valid: int marks; int _total; int age1; ❌ Invalid: int 1 age; int total marks; int int ; 🔹 Types of Variables (Based on Scope) 1️⃣ Local Variable Declared inside a function Used only inside that function void show () { int x = 10 ; } 2️⃣ Global Variable Declared outside all functions Can be used anywhere int x = 10 ; 📌 Data Types in C++ 🔹 What is a Data Type? A data type tells ...
