Arithmetics Q1.Area of Circle for radius 12.5 ? #include <stdio.h> #include <math.h> void main() { float R, area ; R = 12.5; area = M_PI*R*R; printf("area of circle is %f",area); } Using Array : Q2. Sum of given sum of odd and even values? #include<stdio.h> #include<math.h> void main() { int a[10],i,even=0,odd=0; printf("Enter 10 values:"); for(i=0;i<10;i++) { scanf("%d",&a[i]); if(a[i]%2==0) even=even+a[i]; //if(a[i]%2==1) else odd=odd+a[i]; } printf("sum of given even values=%d",even); printf("\nsum of given odd values=%d",odd); }
