Array Program #3

-

6. Read two character arrays from user and concat (concatenate)them one after other in third array and print final
array.

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

void main()
{
     int i,j;
     char a[100],b[100],c[100];
     printf("Enter the first string\n");
     scanf("%s",a);
     printf("Enter the second string\n");
     scanf("%s",b);
     printf("First string  = %s\n", a);
     printf("Second string = %s\n", b);
     i=0;
     while(a[i]!='\0')
     {
          c[i]=a[i];
          i++;
     }
     c[i]=' ';
     i++;
      j=0;
     while(b[j]!='\0')
     {
          c[i]=b[j];
          i++;
          j++;
     }
      c[i]='\0';
     printf("Concatenated string= %s \n",c);
}

OR

#include<stdio.h>
#include<string.h>
void main()
{
     char a[10],b[100];
     printf("Enter the first string\n");
     gets(a);
     printf("Enter the second string\n");
     gets(b);
     printf("First string  = %s\n", a);
     printf("Second string = %s\n", b);
     strcat(a,b);
     printf("Concatenated string= %s \n",c);
}

OR

#include<stdio.h>
#include<string.h>
void main()
{
     char a[100],b[100],c[100];
     printf("Enter the first string\n");
     scanf("%s",a);
     printf("Enter the second string\n");
     scanf("%s",b);
     printf("First string  = %s\n", a);
     printf("Second string = %s\n", b);
     strcat(a,b);
     printf("Concatenated string= %s \n",c);
}

Output

  • Enter the first string
    hello
    Enter the second string
    world
    First string  = hello
    Second string = world
    Concatenated string= hello world

    3.Read any number and find factorial of a number. (Using Recursion) #include <stdio.h> long long int factorial(int n); int main() {     int n;    long long int f;     printf("Enter an integer to find it's factorial: ");     scanf("%d", &n);      // show error if the user enters a negative integer     if (n < 0)     {         printf("Error! Factorial of a negative number doesn't exist.\n");     }     else     {              f=factorial(n);             printf("Factorial of %d = %llu\n", n, f);     } } long long int factorial(int n) {     if (n>=1)     {         return n*factorial(n-1);  ...

    10. Read n numbers in an array and print them using pointer. #include<stdio.h> void main () {      int n,i,*p,array[100];      p=array;      printf("Enter size of array:\n");      scanf("%d",&n);      printf("Enter elements of array:\n");      for(i=0;i<n;i++)      {           scanf("%d",p+i);      }      printf("The array using pointer is:\n");      for(i=0;i<n;i++)      {           printf("%d\n",*(p+i));      } } Output Enter size of array: 5 Enter elements of array : 12 13 14 15 16 The array using pointer is: 12 13 14 15 16 Note: The above method uses array notation to print elements. You can also use poi...
