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;}

3.(a)12 23 3 3 4 4 4 4 5 5 5 5 5

#include <stdio.h>

int main(){

}

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(){

}

85.592.5775.4598.280.2

Input example

Total Sum = 431.92Average = 86.38
