Stack C

This is a simple stack implementation in C, using an array as the underlying data structure. It's possible to resize the stack, and it's possible to set the initial size of the stack.

Functions

• Stack* newStack(int size): Create a new stack with a given size.
• bool isFull(Stack* stack): Check if the stack is full.
• bool isEmpty(Stack* stack): Check if the stack is empty.
• void push(Stack* stack, int item): Push an item onto the stack.
• int pop(Stack* stack): Pop an item off the stack.
• int peek(Stack* stack): Peek at the top of the stack.
• void printStack(Stack* stack): Print the stack.
• void destroyStack(Stack* stack): Destroy the stack.
• char* stackToString(Stack* stack): Convert the stack to a string.
• Stack* resizeStack(Stack* stack, int size): Resize the stack to a new size.

Usage

// Create a stack of capacity 5
Stack* stack = newStack(5);

// Push items to stack
push(stack, 1);
push(stack, 2);
push(stack, 3);
push(stack, 4);
push(stack, 5);

push(stack, 100);

// Check if stack is full
if (isFull(stack)) {
    printf("Stack is full!\n");
}

// Print the stack
printStack(stack);

// Resize the stack
stack = resizeStack(stack, 10);

// Push an item to stack
push(stack, 100);

// Print the stack
printStack(stack);

// Pop items from stack
pop(stack);
pop(stack);

// Convert the stack to string
char* str = stackToString(stack);
printf("%s\n", str);

// Check if the stack is empty
if (isEmpty(stack)) {
    printf("Stack is empty!\n");
} else {
    printf("Stack is not empty!\n");
}

// Peek the top item from stack
printf("Top item: %d\n", peek(stack));

// Destroy the stack
destroyStack(stack);

// Print the stack
printf("%s\n", stackToString(stack));

// Check if the stack is empty
if (isEmpty(stack)) {
    printf("Stack is empty!\n");
} else {
    printf("Stack is not empty!\n");
}
