Number pattern in C language

Question: Write a C program to print the below number pattern

Explanation for number pattern:

From the above image we can see number decreases if the column value is greater than or equal to row value.

Logic:

• Get the input from the user which is n.
• Both the row and column size is n.
• Store the n value into the temp variable to print the pattern
• Decrement the temp value only if column value(j) is greater than or equal to row value(i)
• Repeat the above conditions in a loop to get the pattern

Brief explanation:

• Let us consider input n=5 and then go to the loop to print the pattern
• The outer loop executes for 5 times which is the row size
• And inner loop also do the same but for column size which is 5
• For the first row temp value is 5 and it is not going to decrement because column value (i = 5) is not greater than or equal to column value (j = 4,3,2,1,0)
• In the next row is print the first column value (temp = 5) and then check the condition it is true then decrement the value of (temp = 4) then print remaining column values
• Same thing will happen for remaining rows, at last will get the number pattern

Program:

#include <stdio.h>

int main()
{
    int n;
    int i,j;
    int temp;
    printf("Enter the Input:");
    scanf("%d", &n);

    for (i = n; i > 0; i--)
    {
        temp = n; //Storing the number of rows in a temp variable
        for(j = n - 1; j >= 0; j--)
        {
             printf("%d ",temp); //Print the temp variable start with value (n)
             if(j >= i) //Decrement the temp value only if column value is greater than or equal to row value
                 temp--;
       }
       printf("\n"); //new line to print values in next row
    }

    return 0;
}
