CodeVita – A Perfect Launchpad for Coders by TCS

• Contest is open for students from all institutes, disciplines and batches(1st-4th year) of engineering.
• The students can register for the contest irrespective of any eligibility criteria. To register, visit Campus Commune link on https://nextstep.tcs.com(register as off campus applicant)
• In case, during registration, the student does not find the name of the institute, they can select – “Others” option and then fill the institute name.
• Final round will be held at one of the TCS facilities. Exciting prizes to be won, On the spot offers, on the spot Internship offers may come as a surprise element.
• This time, the students will be competing with institutes from all across the globe, wherever TCS has it’s centers. The last date for registrations is 23rd July,14.

1. Write a ‘C’ program to find the smallest and biggest value in a single dimensional array using array and pointer concepts.
2. write a C program using pointer to sort the given list of numbers in ascending order.

//———————————————— arp2.c ———————————–

// find the sum of array elements using pointer

#include<stdio.h>
void main(){
int a[5];
int *ptr;
int i,sum=0;
printf(“Enter Five Numbers:\n”);
for(i=0;i<5;i++){
scanf( “%d”,&a[i]);
}
ptr=a;
for(i=0;i<5;i++){
sum=sum+*(ptr+i);
}
printf(“Addition is: %d\n”,sum);
