Number patterns are sequences of numbers created according to rules called pattern rules. Pattern rules can use one or more mathematical operations to describe the relationship between consecutive numbers in a sequence.
Pattern Example
Pattern 1
1 2 6 3 7 10 4 8 11 13 5 9 12 14 15
Pattern 2
1 1 2 3 1 2 3 4 5 1 2 3 4 5 6 7 1 2 3 4 5 6 7 8 9 1 2 3 4 5 6 7 1 2 3 4 5 1 2 3 1
Pattern 1: i stands for rows and j stands for columns. 5 stands for making pattern for 5 Rows and Columns Loop for each Row (i) K is initialized to i Loop for each Column (j) Do the Pattern for the current Column (j) Display the Value of K Reinitialize the Value of K = k + 5 - j Pattern 2: First Row: Display 1 Second Row: Display 1,2,3 Third Row: Display 1,2,3,4,5 Fourth Row: Display 1,2,3,4,5,6,7 Fifth Row: Display 1,2,3,4,5,6,7,8,9 Display the same contents from 4th Row till First Row below the fifth Row.
/* Program to print Numeric Pattern */ #includeint main(){ int i,j,k; printf("Numeric Pattern 1"); printf(" "); printf("
"); for(i=1;i<=5;i++){ k = i; for(j=1;j<=i;j++){ printf("%d ", k); k += 5-j; } printf("
"); } printf("
"); printf("Numeric Pattern 2"); printf("
"); printf("
"); for(i = 1;i<=5;i++){ for(j = i;j<5;j++){ printf(" "); } for(k = 1;k<(i*2);k++){ printf("%d",k); } printf("
"); } for(i = 4;i>=1;i--){ for(j = 5;j>i;j--){ printf(" "); } for(k = 1;k<(i*2);k++){ printf("%d",k); } printf("
"); } getch(); return 0; }
