Implementation of Stack using Array

Algorithm for PUSH operation on the stack

Algorithm fnPush(arrSTACK[], Data)
{
if(fnFull()==TRUE)
else
{
top=top+1;
arrSTACK[top]=Data;
}
} // End of Algorithm

 

Algorithm for POP operation from the stack

Algorithm fnPOP(arrSTACK[])
{
if(fnEmpty()==TRUE)
stack is empty;
else
{
Data=arrSTACK[top];
top=top-1;
return Data;
}
} // End of Algorithm
