C Exercises: Find the total number of full staircase rows that can be formed from given number of dices
C Programming Mathematics: Exercise-18 with Solution
Write a C programming to find the total number of full staircase rows that can be formed from given number of dices.
staircase rows format :
Example 1:
n = 5
The dices can form the following rows:
As the 3rd row is incomplete the program will return 2 (full staircase rows).
Example 2:
n = 8
The dices can form the following rows:
As the 4th row is incomplete the program will return 3 (full staircase rows).
Sample Solution:
C Code:
#include <stdio.h>
int check_stair_case(int n) {
if(n<0) return -1;
if(n==0) return 0;
int rows = 0;
long sum = 0;
while(sum<=n){
sum += rows+1;
rows++;
}
return rows-1;
}
int main(void)
{
int n = 5;
printf("Input number %d ",n);
printf("\nTotal number of full staircase rows are %d ",check_stair_case(n));
n = 8;
printf("\nInput number %d ",n);
printf("\nTotal number of full staircase rows are %d ",check_stair_case(n));
return 0;
}
Sample Output:
Input number 5 Total number of full staircase rows are 2 Input number 8 Total number of full staircase rows are 3

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().
