{
printf("\nEligible for Sr KG");}

2) Given below is a C program to display the sum of first 10 natural numbers.
Identify the errors in the program. Rewrite the corrected program and
underline the corrected statement.

#include<conio.h>
void main()
{
int j, sum = 0;
printf("The first 10 natural numbers is :\n");
for (j = 1; j = 10; j)
{
sum = sum + j;
printf("%d ",j);
}
printf(\nThe Sum is : %d\n, sum) getch ( );

{
sum = sum + j;
printf("%d ",j);
}
printf("\nThe Sum is : %d\n", sum);
getch ( );
}
}
