2) Write a program to check if two matrices are equal or not.

 #include<stdio.h>
int main(){
int a[100][100],b[100][100];
int r1,c1,r2,c2,i,j,flag=0;
printf(“enter rows and columns of first and second matrix\n”);
scanf(“%d%d%d%d”,&r1,&c1,&r2,&c2);
printf(“enter elements of first matrix”);
    for(i=0;i<r1;i++){
  for(j=0;j<c1;j++){
scanf(“%d”,&a[i][j]);
    }
 }
printf(“enter elements of second matrix”);
 for(i=0;i<r1;i++){
  for(j=0;j<c1;j++){
scanf(“%d”,&b[i][j]);
  }
 }
if((r1 == r2) && (c1 == c2)){
     for(i=0;i<r1;i++){
   for(j=0;j<c1;j++){
  if(a[i][j] ! == b[i][j]){
  flag = 1;
    }
  }
 }
if(flag == 1)
printf("they are not equal");
else
printf("they are equal");
 }
else{
    printf("they are not equal");
}
}

int r1,c1,r2,c2,i,j,flag=0;

flag = 1;

}

if(flag == 1)

printf("they are not equal");

else

printf("they are equal");

}

else{

printf("they are not equal");

}

4)Write a program using pointer to input 10 numbers and store it in array and sort in ascending order using pointer.

int main(){
    int array[100],n,i,j;
    int *ptr;
    printf("enter size of array\n");
    scanf("%d",&n);
    printf("enter %d elements ",n);
    for(i=0;i<n;i++){
        scanf("%d",&a[i]);
    }
    ptr = &a;
    for(i=0;i<n;i++){
        for(j=i+1;j<n;j++){
            if(*(ptr+i) > *(ptr+j)){
                temp = *(ptr + i);
                *(ptr + i) = *(ptr + j);
                *(ptr + j) = temp;
            }
        }
    }
    printf("the array in sorted order is :");
    for(i=0;i<n;i++){
        printf("%d",a[i]);
    }
}

if(*(ptr+i) > *(ptr+j)){

*(ptr + i) = *(ptr + j);

*(ptr + j) = temp;

}

printf("the array in sorted order is :");

for(i=0;i<n;i++){

5) write a program that reads 2 numbers from user and calculate sum and write it in a file name “sum.dat” […]

year 2014 Q.no 3 Write function that display the factorial of 7 only.

#include<stdio.h>
void fact(int n)
{
    int fact = 1;
    if(n==7)
    {
       for(int i=1;i<=n;i++)
           fact*=i;
       printf("The factorial of 7 is: %d.",fact);
    }
    else
       printf("This function gives the factorial of the number 7 only");
}
void main()
{
    fact(7);
}
Output:
The factorial of 7 is: 5040.

Q.no 4 Write program that takes string as input from the user, and then display the length.

#include<stdio.h>
#include<string.h>
void main()
{
    char srt[50];
    printf("Enter a string:\n");
    gets(str);
    printf("The length of string is %d.",strlen(srt));
