Algorithm, Program, Data Structure and Pseudocode
What is an algorithm? An algorithm is a set of instructions that can be used for solving a problem. An efficient algorithm is the one that takes less running time and memory. Algorithm to swap two numbers: Step 1: Start Step 2: Input two numbers(val1 and val2) Step 3: Assign "val1" to a temporary variable (temp) Step 4: Assign "val2" to "val1" Step 5: Assign "temp" to "val2" Step 6: Display values in val1 & val2 What is a program? Program is nothing but implementation of an algorthim using any programming language(Eg: C, C++, Java etc) C program to swap two numbers: #include<stdio.h> int main() { int val1, val2, temp; printf("Enter two numbers:"); scanf("%d%d", &val1, &val2); temp = val1; val1= val2; val2 = temp; printf("After swapped: %d %d\n", val1, va2); return 0; } What is a pseudocode? It is a combination of both natural and programming
