1.Doiraning yuzini hisoblovchi funksiya hosil
qiling .Bu funksiya yordamida 3 ta doira yuzini hisoblang
DASTUR KODI:
# include
# include
void Yuza(){
using namespace std;
bool a=true;
while(a){
float pi=3.14, radius,yuza=0;
cout<<"doira radiusini kiriting ->";
cin>>radius;
yuza=pi*radius*radius;
cout<<"Doira yuzasi="<}
}
int main(){
using namespace std;
Yuza();
}
2-Berilgan n uchun s ning qiymati hisoblansin
S=1!-2!+3!-4!+….+(-1)^(n+1)*n!
# include
# include
int main(){
using namespace std;
int a,b,c,d;
int summ=0;
int ozgar=1;
cout<<" Chegarani kiriting->";
cin>>a;
for( int i=1; i<=a;i++){
ozgar=1;
for( int j=1;j<=i;j++){
ozgar*=j;
}
summ+=pow(-1,(i+1))*ozgar;
}
cout<}

3-Butun sonlar ketma ketligi kiritiladi 0 ketma ketliknibng oxiri ketma ketlikdagi 7 karra va 5 ga karra bo’lmagan sonalar sonini va manfiy sonlarni aniqlang

# include
# include
int main(){
using namespace std;
int a,b,c,d;
int summ=0;
int ozgar=0;
bool s=true;
while(s){
cout<<" sonni kiriting->";
cin>>a;
if(a%7>0 && a%5>0){
summ++;
}
if(a<0){
ozgar+=a;}
if(a==0){
s=false;
break;
}
}
cout<cout<}
