Program to print number pattern in C
Program Description
A numerical pattern is a sequence of numbers that have been created based on a rule called a pattern rule. Pattern rules can use one or more mathematical operations to describe the relationship between consecutive numbers in the sequence.
Examples for Patterns
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
1Algorithm
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.
Example
/* Program to print Numeric Pattern */
#include<stdio.h>
int 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;
}Output
