**With arrays and function sort:**

#include<stdio.h>

#include<algorithm> //for sort()

int main()

{

int a[3],i;

printf("Input 3 integers: ");

for(i=0;i<3;i++)

{

scanf("%d",&a[i]);

}

std::sort(&a[0],&a[3]);//sorts elements between a[0] and a[3] not including a[3]

printf("Two smallest integers are %d and %d.",a[0],a[1]);

return 0;

}

**Without arrays and sort:**

#include<stdio.h>

int main()

{

int a,b,c;

printf("Input 3 integers: ");

scanf("%d %d %d",&a,&b,&c);

if(a>b)

if(a>c)

printf("Two smallest integers are %d and %d.",b,c);

else

printf("Two smallest integers are %d and %d.",b,a);

else if(b>c)

printf("Two smallest integers are %d and %d.",a,c);

else

printf("Two smallest integers are %d and %d.",a,b);

return 0;

}
