Exercise 2 : Using for loop Repetition (loop)
(1) control variable initialization(2) Test Conditon(3) Modification of control variable value
order : (1) (2) body (3) (2) body (3) (2) body … body (3) (2)
* Example
for ( (1); (2); (3) ) { // for-repetition body
. . . .
. . . . // {} is not necessary // if there is only one statement in body}
int main(){
for(counter = 1; counter <= 10; counter++ )printf(“%d\n”,counter);
}
1. Write a program that calculates the squares and cubes of the numbers from 0 to 10 and prints the following table of values. (Be careful of the alignment.)
number square cube 0 0 0 1 1 1 2 4 8 3 9 27 4 16 64 5 25 125 6 36 216 7 49 343 8 64 512 9 81 729 10 100 1000
#include <stdio.h>
int main(){ int n , i; int sum=0;
scanf("%d",&n); for (i=1;i<=n;i++) { sum+=i; } printf("%d\n",sum);
return 0;}
2.(a) Given an integer number n as a user input, compute and print
Sum(n)=1+2+3+…+n
#include <stdio.h>
int main(){
}
2.(b) Given an integer number n as a user input, compute and print the product of odd numbers between 1 and n. Assume n is less than 20.
Result : 1*3*…*n (if n is odd) 1*3*…*n-1 (if n is even)
#include <stdio.h>
int main(){ int i , j; for (i=1;i<=5;i++) { for (j=1;j<=i;j++) { printf("%d ",i); } printf("\n"); } return 0;}

4. Write a C program that calculates and prints the total sum and average of 5 floating point values that are taken as user input.
#include <stdio.h>
int main(){
