Question

At the beginning of the program and before each function use comments to explain what the function does. Do not use global variables 1. The Pascal triangle can be used to compute the coefficients of the terms in the expansion of atb In a Pascal triangle, each element is the sum of the element directly above it and the element to the left of the element directly above it (if any) An example of a triangle of size 7 is shown below: 10 105 15 20 15 6 Declare a two-dimensional array in function main (allow the array to contain up to 25 rows and 25 columns) and initialize elements to 0. Have the user input the size of the Pascal triangle (up to 25). (The triangle will have the same number of rows as columns To facilitate the printing of the resulting triangle, it will be better to keep the size at 10 or ess Compute the coefficients of the Pascal triangle of the size entered using a nested loop Print the triangle from function main (do not print the elements that have been initialized to 0 but are not part of the triangle). This program may be written entirely in function main Hint: Note that mangl [0][0]. triangle column 0 are equal to 1 , triangle as well as all other values in

Hi there I need help coming up with the C code for this problem.

Answer 1

Code -

#include <stdio.h>
//function declared
long fact(int);

int main()
{
//varibale declared
int i, n, c;
//ask use to enter numver of rows for pascal triangle
printf("Enter the number of rows in pascal triangle\n");
scanf("%d",&n);
//print the pascal triangle
//outer loop for row iteration
for (i = 0; i < n; i++)
{
//inner loop to print the value for pascal triangle
for (c = 0 ; c <= i; c++)//formula to calulate value at every point in pascal triangle
printf("%ld ",fact(i)/(fact(c)*fact(i-c)));

printf("\n");
}

return 0;
}
//calculate the factorial and return it value
long fact(int n)
{
int c;
long result = 1;

for (c = 1; c <= n; c++)
result = result*c;

return result;
}
