C Exercises: Print first 50 natural numbers
C Recursion : Exercise-1 with Solution
Write a program in C to print first 50 natural numbers using recursion.
Pictorial Presentation:
Sample Solution:
C Code:
#include<stdio.h>
int numPrint(int);
int main()
{
int n = 1;
printf("\n\n Recursion : print first 50 natural numbers :\n");
printf("-------------------------------------------------\n");
printf(" The natural numbers are :");
numPrint(n);
printf("\n\n");
return 0;
}
int numPrint(int n)
{
if(n<=50)
{
printf(" %d ",n);
numPrint(n+1);
}
}
Sample Output:
Recursion : print first 50 natural numbers : ------------------------------------------------- The natural numbers are : 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

C Programming: Tips of the Day
Static variable inside of a function in C
The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().
The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.
The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
