Graph C/C++ Programs Last Updated : 23 Jul, 2025 Comments Improve Suggest changes Like Article Like Report Graph algorithms are used to solve various graph-related problems such as shortest path, MSTs, finding cycles, etc. Graph data structures are used to solve various real-world problems and these algorithms provide efficient solutions to different graph operations and functionalities. In this article, we will discuss how to implement various graph algorithms in C/C++. Prerequisite: Graph Data Structure Graph Algorithm Programs in C/C++The following is the list of C/C++ programs based on the level of difficulty: EasyDepth First Search or DFS for a Graph Breadth First Search or BFS for a Graph Find Whether there is Path Between two Cells in Matrix Shortest Path in a Binary Maze Print All Paths from a Given Source to a Destination Find if There is a Path Between Two Vertices in a Directed Graph Find a Mother Vertex in a Graph Transitive Closure of a Graph Eulerian Path in Undirected Graph Detect Cycle in an Undirected Graph MediumDetect Cycle in a Directed Graph Find the Number of Islands Using DFS Introduction to Disjoint Set Data Structure or Union-find Algorithm Union by Rank and Path Compression in Union-find Algorithm How to Find Shortest Paths From Source to All Vertices Using Dijkstra’s Algorithm Kruskal’s Minimum Spanning Tree (MST) Algorithm Check if a Graph is Strongly Connected | Set 1 (Kosaraju Using DFS) Minimum Time Required to Rot All Oranges Floyd Warshall Algorithm | DP-16 Connected Components in an Undirected Graph HardCheck Whether a Given Graph is Bipartite or Not Topological Sorting Shortest Path in Directed Acyclic Graph Transitive Closure of a Graph Articulation Points (or Cut Vertices) in a Graph Bridges in a Graph Biconnected Graph Strongly Connected Components Hamiltonian CycleMinimum Cost Path with Left, Right, Bottom, and Up Moves Allowed Create Quiz Comment R rahulsharmagfg1 Follow 0 Improve R rahulsharmagfg1 Follow 0 Improve Article Tags : C++ C Graph Programs C++ Graph Programs Explore C++ BasicsIntroduction to C++3 min readData Types in C++6 min readVariables in C++4 min readOperators in C++9 min readBasic Input / Output in C++3 min readControl flow statements in Programming15+ min readLoops in C++7 min readFunctions in C++8 min readArrays in C++8 min readCore ConceptsPointers and References in C++5 min readnew and delete Operators in C++ For Dynamic Memory5 min readTemplates in C++8 min readStructures, Unions and Enumerations in C++3 min readException Handling in C++12 min readFile Handling in C++8 min readMultithreading in C++8 min readNamespace in C++5 min readOOP in C++Object Oriented Programming in C++8 min readInheritance in C++6 min readPolymorphism in C++5 min readEncapsulation in C++3 min readAbstraction in C++4 min readStandard Template Library(STL)Standard Template Library (STL) in C++3 min readContainers in C++ STL2 min readIterators in C++ STL10 min readC++ STL Algorithm Library3 min readPractice & ProblemsC++ Interview Questions and Answers1 min readC++ Programming Examples4 min read Like
