Assignment_01: Basic C Programming with Rstudio

1 Exercise 1

1.1 C Code

#include <stdio.h>
int main() {
    int kk, termnumber, term1 = 0, term2 = 1, term3 ;
    printf("enter the number of terms you want to display : ");
    scanf("%d", & termnumber);
    printf("Display Fibonacci Series: ");

    for (kk = 1; kk <= termnumber; ++kk) {
        printf("%d, ", term1);
        term3 = term1 + term2;
        term1 = term2;
        term2 = term3;
    }

    return 0;
}

2.1 C Code

#include <stdio.h> 
  
double harmonicsum(int term) 
{ 
  double jj,  ss = 0.0; 
  for (jj = 1; jj <= term; jj++) 
      ss = ss + 1/jj; 
  return ss; 
} 
  
int main() 
{ 
    int kk, termnumber ;
    printf("enter the term number of harmonic series  you want to display : ");
    scanf("%d", &termnumber);
    printf("For the given integer = %d \n", termnumber );
    for (kk = 1; kk <= termnumber; kk++) 
       printf("n = %d :  Harmonic Sum  is %f \n", kk,  harmonicsum(kk));
    return 0;

    ss = 0;
    while (ss < sum_harmonic_series){ 
           ss = ss + (1/(float)kk);
