Displaying the Stack Contents

To view the entire stack content, the following function, info, can be used:

1
2
3
4
5
6
7
8
fn info()                                                                        
{                                                                                
    printf("stack: ");                                                           
    for (local i: int = 0; i < stackSize; ++i) {                                 
        printf("[%d] ", stack[i]);                                               
    }                                                                            
    printf("\n");                                                                
}

Modify the instructions in main so that after each push/pop operation, the top element and the entire stack content are displayed, producing output similar to the following:

1
2
3
4
5
6
7
lehn$ ./a.out 
top = 3
stack: [3] 
top = 4
stack: [3] [4] 
top = 3
stack: [3]
