2d array

1. Given two matrices of order M1*N1 and M2*N2. Write function to perform matrix multiplication and display the resultant matrix if matrix multiplication is possible otherwise display the message "Invalid Matrices".  Sol: #include int main()  {  i nt m, n, p, q, c, d, k, sum = 0;   int first[10][10], second[10][10], z[10][10];  printf("\nEnter the number of rows and columns of first matrix:\n");   scanf("%d%d", &m, &n);   printf("\nEnter the number of rows and columns of second matrix:\n");   scanf("%d%d", &p, &q);  if ( n != p )  {  printf("\nMatrices with entered orders can't be multiplied with each other.\n");   printf("\nThe column of first matrix should be equal to row of second.\n");   }  else   {   printf("\nEnter the elements of first matrix:\n");   for ( c = 0 ; c < m ; c++ )   for ( d = 0 ; d < n ; d++ )  scanf...

recursions

 1. Srujan asks his son Arun to calculate the sum of total natural numbers present on the board.  Arun starts summing the natural numbers and after reaching up to 10 he gets confused and  again starts counting from first. Your task is to help Arun to calculate the sum of n natural  numbers recursively Sol:   #include<stdio.h>  int sum(int n);  int main()  {  int n;  scanf("%d",&n);  printf("sum of natural numbers=%d\t",sum(n));  return 0;  }  int sum(int n)  {  if(n==0)  { return 0;  }  else if(n==1)  {  return 1;  }  else { return (n+sum(n-1)); } } 2.Write a recursive module to find factorial of a given number. Sol:  #include<stdio.h>  long int fact(int n);  int main()  {  int n;  scanf("%d",&n);  printf("factorial of a given number=%ld",fact(n));  return 0;  }  long int fact(n)  { if(n==0||n==...
