PROGRAM - 8

a)  Write a program to find the largest and smallest number in a list of integers.

Program:

#include<stdio.h>

#include<conio.h>

void main()

{

    int rng[50],i,n,lrg,sml;

    clrscr();

    printf("enter the range");

    scanf("%d",&n);

    for(i=0;i<n;i++)

    {

     printf("enter %d element \n",i+1);

     scanf("%d", &rng[i]);

    }

    lrg=rng[0];

    sml=rng[0];

    for(i=0;i<n;i++)

    {

     if(rng[i]>=lrg)

     lrg=rng[i];

     if(rng[i]<=sml)

     sml=rng[i];

    }

    printf("the smallest number in range %d",sml);

    printf("\nthe largest number in range %d",lrg);

    getch();

}

/*

INPUT:enter the range:5

enter 1 element 5

enter 2 element 8

enter 3 element 9

enter 4 element 23

enter 5 element 1

OUTPUT:

the smallest number in range 1

the largest number in range 23

*/

b)  Write a program to perform the following:

ü  Addition of two matrices.

ü  Multiplication of two matrices.

Program for matrix addition:

#include<stdio.h>

#include<conio.h>

main()

{

     int a[10][10],b[10][10],c[10][10],i,j,r1,r2,c1,c2;

     clrscr();

     printf("enter rows and columns of A&B\n");

     scanf("%d %d %d %d",&r1,&c1,&r2,&c2);

     if(r1==r2&&c1==c2)

     {

        printf("Enter matrix A elements\n");

        for(i=0;i<r1;i++)

        {

        for(j=0;j<c1;j++)

        {

          c[i][j]=a[i][j]+b[i][j];

          printf("%d\t",c[i][j]);

        }

        printf("\n");

        }

     }

     getch();

}

/*
