Bit Integers in C

I am just trying to do a problem in C that may give us 64 bit integers. It cannot support in displaying such big number. So what can i do?

#include<stdio.h>
#include<string.h>
#include<math.h>
#include<stdlib.h>

int main() {
/* Enter your code here. Read input from STDIN. Print output to STDOUT */
long int a,b,n,c;
scanf("%ld %ld %ld",&a,&b,&n);
n-=2;
while(n--){
    c=(b*b)+a;
    a=b;
    b=c;
}
printf("%ld",c);
return 0;
}

You should use %lld.

scanf("%lld %lld %lld",&a,&b,&n);
printf("%lld",c);

But long int is not an 64bit integer. Use long long int or int64_t from inttypes.h.
