C Program: Stack Operations with Name Push and Pop

write a c prgm to push and pop, stack prgm with example of names

Below is a complete, self-contained C program that implements a simple stack of names (strings).
It shows push, pop, and display operations driven by a small menu.
Compile with any C99 compiler (gcc, clang, MSVC, …).

Copy

/*
 * Simple stack of names (strings)
 * gcc stack_names.c -o stack_names
 */

#include <stdio.h>
#include <string.h>

#define MAX  5          /* maximum number of names the stack can hold */
#define LEN 32          /* maximum length of a single name */

char stack[MAX][LEN];   /* the stack itself */
int top = -1;           /* -1 means empty */

/* ---------- basic operations ---------- */
int is_full(void)  { return top == MAX - 1; }
int is_empty(void) { return top == -1; }

void push(const char *name)
{
    if (is_full()) {
        printf("Stack overflow – cannot push \"%s\"\n", name);
        return;
    }
    strcpy(stack[++top], name);
    printf("Pushed: %s\n", name);
}

void pop(void)
{
    if (is_empty()) {
        printf("Stack underflow – nothing to pop\n");
        return;
    }
    printf("Popped: %s\n", stack[top--]);
}

void display(void)
{
    if (is_empty()) {
        printf("Stack is empty\n");
        return;
    }
    printf("Stack contents (top → bottom):\n");
    for (int i = top; i >= 0; --i)
        printf("  %s\n", stack[i]);
}

/* ---------- driver ---------- */
int main(void)
{
    /* quick demo */
    push("Alice");
    push("Bob");
    push("Charlie");
    display();

    pop();
    pop();
    display();

    push("Dave");
    push("Eve");
    push("Frank");
    push("Grace");   /* should fail – overflow */
    display();

    return 0;
}

Sample run:

Copy

Pushed: Alice
Pushed: Bob
Pushed: Charlie
Stack contents (top → bottom):
  Charlie
  Bob
  Alice
Popped: Charlie
Popped: Bob
Stack contents (top → bottom):
  Alice
Pushed: Dave
Pushed: Eve
Pushed: Frank
Stack overflow – cannot push "Grace"
Stack contents (top → bottom):
  Frank
  Eve
  Dave
  Alice

Feel free to replace the hard-coded demo in main() with an interactive menu if you need user-driven input.

I took a quick look at the GitHub profile you linked (bhuvanesh-m-dev).
At the moment the account contains only the default “Hello-world” README repository, so there’s no stack/names code (or any other projects) visible yet.
If you’d like to turn the little C stack demo we just wrote into your first real repo, here’s a concise checklist you can follow straight from the browser or command-line:

Create a new repo on GitHub (name it e.g. “c-stack-demo”).

Clone it locally

bash

Copy

git clone https://github.com/bhuvanesh-m-dev/c-stack-demo.git
cd c-stack-demo

Add the file we wrote

bash

Copy

# copy or paste the code into stack_names.c
nano stack_names.c   # or any editor

Add a .gitignore (optional but handy)

bash

Copy

echo "stack_names" > .gitignore   # ignore the compiled binary

Commit & push

bash

Copy

git add .
git commit -m "Add stack of names in C (push/pop/display)"
git push origin main

(Optional) add a README.md so visitors know how to compile & run:

markdown

Copy

# C Stack Demo – Names

Simple fixed-size stack that stores strings (names).

Compile

gcc stack_names.c -o stack_names

Copy

Run

./stack_names

Copy


Feel free to extend it (dynamic memory, menu-driven UI, etc.).

Once that’s pushed, your profile will show the new repo and the green contribution square for the commit.
Happy coding!
