Hello! In this guide, I want to tell you about one of the most widely used data structures in C++. This is a type called queue.<\/p>\n

The queue is a data structure organized on the principle of FIFO (first in \u2013 first out). We can compare it with the array of the element \u2013 the difference is just in capabilities. It looks like this:<\/p>\n

\"\"<\/a><\/p>\n

Let\u2019s try to create one! We will fill it with a huge number and then output it on the screen:<\/p>\n

So, first we need to create a data structure:<\/p>\n

[code language=”cpp”]
\nstruct number {
\n\tint value;
\n\tnumber *next;
\n}
\n[\/code]<\/p>\n

The difference between the queue and the stack is that we should allocate the memory for the first element from the beginning:<\/p>\n

[code language=”cpp”]
\nnumber *top, *p, *first; \/\/ create pointers
\ntop = new number; \/\/ allocate the memory for the first element
\ntop->next = NULL; \/\/ now it\u2019s the last one too, so the pointer to the next element is NULL
\nfile >> top->value; \/\/ read the data from the text file
\nfirst = top; \/\/ save the address of the first element
\ndo {
\n\tp = new number; \/\/ allocate memory for the new element
\n\tp->next = NULL; \/\/ since it\u2019s the last now, the next element is NULL
\n\tfile >> p->value; \/\/ read the data from the text file
\n\ttop->next = p; \/\/ attach the new element to the previous
\n\ttop = p; \/\/ move the second pointer
\n} while (top->value); \/\/ repeat the cycle until the file is over
\nIn this way we have filled our queue with the data from the file. Now let\u2019s try to output it:
\ntop = first; \/\/ choose the first element
\ntop = first; \/\/ choose the first element
\ndo {
\n\tcout << top->value; \/\/ output the data
\n\ttop = top->next; \/\/ move to the next element
\n} while (top != NULL); \/\/ repeat the cycle until the text file is over
\n[\/code]<\/p>\n

Now we are able to create a dynamic data structure called queue, read from the text file, and output it.<\/p>\n
