Q//W. P. to find y value: #include<iostream. h> #include<math. h> void main() { int i, j, n, x, r; double y; r=1; cin>>x>>n; for(i=2; i<=n; i+=2) { y+=(pow(x, i)/i)*r; r*=-1; } cout<<"y="<<y; } ﺍﺫﺍ ﻛﺎﻥ ﺍﻭﻝ ﺣﺪ ﺳﺎﻟﺐ ﻳﺠﺐ ﺍﻥ ﺗﻜﻮﻥ r = -1 A. L. Waleed Rasheed
Q / write a program to read the 100 number, and then calculate the average to positive elements and negative elements? #include<iostream. h> void main() { int i, x, k 1, s 1, k 2, s 2; k 1=k 2=s 1=s 2=0; for(i=1; i<=100; i++) { cin>>x; if(x>=0) { s 1+=x; k 1++; } else { s 2+=x; k 2++; } } cout<<"average to Pos. No. ="<<s 1/k 1; cout<<"n average to Neg. No. ="<<s 2/k 2; } A. L. Waleed Rasheed
Q / write a program to read the 100 number, and then calculate the average even positive elements? #include<iostream. h> void main() { int i, x, k 1, s 1; k 1=s 1=0; for(i=1; i<=100; i++) { cin>>x; if(x>=0 && x%2==0) { s 1+=x; k 1++; } } cout<<"average to even Pos. No. ="<<s 1/k 1; } A. L. Waleed Rasheed
