Exercise 2 : Using for loop

(1) FALSE (2) TRUE body (3) Exercise 2 : Using for loop • Repetition (loop) • control variable initialization • Test Conditon • Modification of control variable value order : (1) (2) body (3) (2) body (3) (2) body … body (3) (2) * Example for ( (1); (2); (3) ) { // for-repetitionbody . . . . . . . . // {} 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

2.(a) Given an integer number n as a user input, compute and print Sum(n)=1+2+3+…+n 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 n , i; int sum=0; scanf("%d",&n); for (i=1;i<=n;i++) { sum+=i; } printf("%d\n",sum); return 0; } #include <stdio.h> int main() { }

3.(a) 1 2 2 3 3 3 4 4 4 4 5 5 5 5 5 3.(b) * * * * * * * * * * * * * * * #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; } #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() { } Input example output example 85.5 92.57 75.45 98.2 80.2 Total Sum = 431.92 Average = 86.38
