In this tutorial, we will discuss a concept of C program to Integrated triangle patterns using for loop
In C language, we can use for loop ,while loop and do-while loop to display different number (binary, decimal), alphabets or star pattern programs.
In this article, we are going to learn how to Display Integrated triangle patterns using for loop in C language
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,k,rows;
printf("Enter the number of rows: ");
scanf("%d",&rows); //get input from user for rows
for(i=1; i<=rows; i++){ //parent for loop
for(j=1; j<=i; j++){
printf("*");
}
for(j=i*2; j<rows*2; j++){
printf(" ");
}
for(k=i; k>=1; k--){
printf("*");
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 2
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,k,rows;
printf("Enter the number of rows: ");
scanf("%d",&rows); //get input from user for rows
for(i=rows; i>=1; i--){ //parent for loop
for(j=rows; j>=1+rows-i; j--){
printf("*");
}
for(j=i*2; j<rows*2-1; j++){
printf(" ");
}
for(k=1+rows-i; k<=rows; k++){
if(k!=1)
printf("*");
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 1
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,k,rows;
printf("Enter the number of rows: ");
scanf("%d",&rows); //get input from user for rows
for(i=1; i<=rows; i++){ //parent for loop
for(j=1; j<=i; j++){
printf("%d",j);
}
for(j=i*2; j<rows*2; j++){
printf(" ");
}
for(k=i; k>=1; k--){
printf("%d",k);
}
printf("\n");
}
getch();
return 0;
}

printf(" ");
}
for(k=1+rows-i; k<=rows; k++){
if(k!=1)
printf("%d",k);
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
Program 3
#include <stdio.h>
#include <stdlib.h>
int main()
{
int i,j,k,rows;
printf("Enter the number of rows: ");
scanf("%d",&rows); //get input from user for rows
for(i=rows; i>=1; i--){
for(j=1; j<=i; j++){
printf("%d",j);
}
for(j=i*2; j<rows*2-1; j++){
printf(" ");
}
for(k=i; k>=1; k--){
if(k!=rows)
printf("%d",k);
}
printf("\n");
}
getch();
return 0;
}
When the above code is executed, it produces the following results
