Program to print right and left arrow patterns in C
Program Description
Print the Right and Left arrow Patterns
Algorithm
Accept the number of rows to print the Left and Right Arrow Pattern.
Print Upper Part of the Arrow with Stars Patterns Print Inverted Right Triangle with Stars Patterns Print Bottom Part of the Arrow with Stars Patterns Print the Right Triangle with Stars Patterns
Example
/*Program to print the Left and right arrow pattern*/
#include<stdio.h>
int main() {
int r, c, rows; //Left Arrow Pattern
int r1, c1, rows1; //Right Arrow Pattern
clrscr();
printf("Enter number of rows to print the Left Arrow Pattern: ");
scanf("%d", &rows);
printf("
");
printf("The Left Arrow Pattern is:");
printf("
");
for(r=1; r<rows; r++){
for(c=1; c<=(rows-r); c++){
printf(" ");
}
for(c=r;c<=rows; c++){
printf("*");
}
printf("
");
}
for(r=1; r<=rows; r++){
for(c=1; c<r; c++){
printf(" ");
}
for(c=1; c<=r; c++){
printf("*");
}
printf("
");
}
printf("Enter number of rows to print the Right Arrow Pattern: ");
scanf("%d", &rows1);
printf("
");
printf("The Right Arrow Pattern is:");
printf("
");
for(r1=1; r1<rows1; r1++){
for(c1=1; c1<=(2*r1-2); c1++){
printf(" ");
}
for(c1=r1; c1<=rows1; c1++){
printf("*");
}
printf("
");
}
for(r1=1; r1<=rows1; r1++){
for(c1=1; c1<=(2*rows1 - 2*r1); c1++){
printf(" ");
}
for(c1=1; c1<=r1; c1++){
printf("*");
}
printf("
");
}
getch();
return 0;
}Output
