6) Write a C program to add all elements of a matrix by using dynamic memory allocation.
#include<stdio.h>
#include<stdlib.h>
int main()
{
int *ptr; //declaration of integer pointer
int limit; //to store array limit
int i; //loop counter
int sum; //to store sum of all elements
printf("Enter limit of the array: ");
scanf("%d",&limit);
//declare memory dynamically
ptr=(int*)malloc(limit*sizeof(int));
//read array elements
for(i=0;i
{
printf("Enter element %02d: ",i+1);
scanf("%d",(ptr+i));
}
//print array elements
printf("\nEntered array elements are:\n");
for(i=0;i
{
printf("%d\n",*(ptr+i));
}
//calculate sum of all elements
sum=0; //assign 0 to replace garbage value
for(i=0;i
{
sum+=*(ptr+i);
}
printf("Sum of array elements is: %d\n",sum);
//free memory
free(ptr); //hey, don't forget to free dynamically allocated memory.
return 0;
}
