Not getting output

#include<stdio.h> int main() { int a[30],*n,i,size; printf("\n enter the no of elements:"); scanf("%d",&size); n=a; printf(" unsorted array is :"); for(i=0;i<size;i++) { scanf("%d \t",n+i); } sort(size,n); } int sort(int size,int *p) { int i,j,t,k; for(i=1;i<size;i++) { for(j=0;j<size-1;j++) { if(*(p+j)>*(p+j+1)) { t=*(p+j); *(p+j)=*(p+j+1); *(p+j+1)=t; } } } printf("\n sorted array is:"); for(k=0;k<size;k++) { printf("%d \t",*p+k); } }

Input something like this: 5 3 4 5 2 1 Some minor mistakes: 1) the return type of sort function is int but you didn't return anything, so better make it void. 2) its a good practice to declare and define a function before main function. 3) printf("%d \t",*p+k); must be printf("%d \t",*(p+k));

If you are trying to dereference something like *p+k, you have to make it inside parenthesis like that: *(p+k). *p+k makes you add k to the first element of your p array, while *(p+k) make you move the iterator to the next element, as p points to the first element, and k moves iterator by k elements forward. By the way you have to declare your function "sort" before you write it in main. (add "int sort (int, int*); between your headers and main function). Same about scanf. But you do not have to dereference it with asterisk. You can also write just n[i]-in scanf, and p[k]-in printf instead. If you want to, you can avoid making unnecessary variable a[30], by allocating memory dynamically to *n. It would look like this: n=(int*)malloc(sizeof(int)*size); Then you will have array n that can store "size" elements
