Write a c program to print Floyd’s triangle

1. Write a c program to print Floyd’s triangle

2. C program to display Floyd’s triangle

3. How to print Floyd’s triangle in c

#include<stdio.h>

int main(){

  int i,j,r,k=1;

  printf("Enter the range: ");

  scanf("%d",&r);

  printf("FLOYD'S TRIANGLE\n\n");

  for(i=1;i<=r;i++){

      for(j=1;j<=i;j++,k++)

           printf(" %d",k);

      printf("\n");

  }

  return 0;

}

C code for factorial of a number

Code 1:

1. C code for factorial of a number

2. C program to find the factorial of a given number

3. Factorial program in c using while loop
4. Factorial program in c without using recursion

#include<stdio.h>

int main(){

  int i=1,f=1,num;

  printf("Enter a number: ");

  scanf("%d",&num);

  while(i<=num){

      f=f*i;

      i++;

  }

  printf("Factorial of %d is: %d",num,f);

  return 0;

}

Sample output:

Enter a number: 5

Factorial of 5 is: 120

WRITE A C PROGRAM to concatinate of two string

#include <stdio.h>
#include <string.h>

int main()
{
    char a[100], b[100];
   
    printf("Enter the first string\n");
    gets(a);
   
    printf("Enter the second string\n");
    gets(b);
   
    strcat(a,b);
   
    printf("String obtained on concatenation is %s\n",a);
   
    return 0;

}

program for addition of two matrices using arrays

 

 #include<stdio.h>

int main(){

  int a[3][3],b[3][3],c[3][3],i,j;

  printf("Enter the First matrix->");

  for(i=0;i<3;i++)

      for(j=0;j<3;j++)

           scanf("%d",&a[i][j]);

  printf("\nEnter the Second matrix->");

  for(i=0;i<3;i++)

      for(j=0;j<3;j++)

           scanf("%d",&b[i][j]);
