Algorithm
- Print the first row of numbers from 1 to Num.
- After that, from the second to the (Num-1)th row, print 2 * (Num- in- 1) blank spaces followed by the concluding element, in- 1 .
- Display the last row with numbers ranging from 1 to Num .
Program to print z pattern:
Example
// implementation of Z pattern
#include <stdio.h>
// Programme to print the required
// Alphabetic Z Pattern
void alphabetZpattern(int Num)
{
int in, side_indexs, sizes;
// Identifying the values for Right,
// Left, as well as Diagonal
int Tops = 1, down = 1, Diag = Num - 1;
// Loop for printing the first row
for (in = 0; in < Num; in++)
printf("%d ", Tops++);
printf("\n");
// loop iterating over the indexes
for (in= 1; in< Num - 1; in++) {
// loop iteration
for (side_indexs = 0; side_indexs < 2 * (Num - in - 1);
side_indexs++)
printf(" ");
// displaying the diagonal values
printf("%d", Diag--);
printf("\n");
}
// loop iterating over the last row
for (in= 0; in < Num; in++)
printf("%d ", down++);
}
// Driver Code
int main()
{
// initialize the n with size
int N = 6;
alphabetZpattern(N);
return 0;
}

Explanation:
- In this program, the alphabetic Z pattern is printed with this function. It accepts one input Num , the size of the Z pattern to be produced.
- Variables:
- This variable acts like a loop counter during multiple loops .
- side_indexes: This variable specifies the number of spaces to be printed on either side of the diagonal.
- sizes: These are not used in the program.
- Tops: This variable represents the values displayed in the Z pattern's top row.
- down: It indicates what values will be printed in the Z pattern's bottom row.
- Diag: The diagonal values are represented by this variable.
- It displays the first row of integers ranging from 1 to Num (in this example, 1 to 6).
- After that, the diagonal element of the Z pattern is printed, with gaps on both sides and decreasing numerals from Num-1 to 1 .
- Finally, it displays the bottom row containing numbers ranging from 1 to Num .
