Write a program to find the geometric progression in c?

Answer 1

#include(stdio.h) // place this '<' & '>' instead of '(' & ')' before stdio.h

#include(conio.h)

#include(math.h)

int main( )

{

int x, n, sum,power;

clrscr( );

printf("Enter the values of x and n:");

scanf("%d%d", &x, &n);

if(n<0 style="font-weight: bold; color: rgb(255, 0, 0);">

{

printf("\nSorry, the formula does not make sense for negative exponents & values");

printf("Enter the values of x and n:");

scanf("%d%d", &x, &n);

sum=1;

for(power=1; power <=n; power++) {

sum=sum+ pow(x,power); }

printf("X value is: %d \nN value is: %d", x, n);

printf("\nSum of the given geometric progression: %d", sum);

}

else

{

sum=1;

for(power=1; power <=n; power++) {

sum=sum+ pow(x,power); }

printf("X value is: %d \nN value is: %d", x, n);

printf("\nSum of the given geometric progression: %d", sum);

}

getch( );

return 0;

}
