Write a C program to addition of two matrices.

Answer:

#include<stdio.h>
#include<conio.h>
main()
{
	int a[10][10],b[10][10],c[10][10],m,n,p,q,i,j;
	printf("\n Enter the dimension of the 1st matrix");
	scanf("%d %d",&m,&n);
	printf("\n Enter the dimension of the 2nd matrix");
	scanf("%d %d",&p,&q);
	if(m!=p||n!=q)
	 printf("\n Error in input, we can't add.Dimension must be equal.");
	else
	 {
	 	printf("\n Enter the elements of 1st matrix");
	 	for(i=0;i<m;i++)
	 	{
	 		for(j=0;j<n;j++)
	 	 	 scanf("%d",&a[i][j]);
	 	}
	 	printf("\n Enter the elements of 2nd matrix");
		for(i=0;i<p;i++)
		{
			for(j=0;j<q;j++)
			 scanf("%d",&b[i][j]);	
		} 
		for(i=0;i<m;i++)
		{
			for(j=0;j<n;j++)
			 c[i][j]=a[i][j]+b[i][j];
		}
		printf("\n The result matrix is :\n");
		for(i=0;i<m;i++)
		{
			for(j=0;j<n;j++)
			 printf("%d\t",c[i][j]);
			printf("\n"); 
		}
	 } 
	 getch();

The total distance travelled by vehicle in 't' seconds is given by distance = ut+1/2at^2 where 'u' and 'a' are the initial velocity (m/sec.) and acceleration (m/sec2).

Write C program to find the distance travelled at regular intervals of time given the values 'u' and 'a'.

The program should provide the flexibility to the user to select his own time intervals and repeat the calculations for different values of 'u' and 'a'.
