2. 
   char turidagi A satrdagi har bir verguldan oldin, B satrdagi o’zlarni joylashtirish natijasida S satrini hosil qiluvchi dastur tuzing.
   

Dastur kodi:

#include

using namespace std;
void printString(string str, char ch, int count)
{
int occ=0, i;
if(count==0) {
cout< return;
}
for(i=0; i if(str[i]==ch)
occ++;
if (occ==count)
break;
}
if (i cout< else
cout<<"bo'sh satr topilmadi";
}
int main()
{
string str="bo'sh satr";
printString(str,'e',2);
return 0;
}

3.String turidagi Satr berilgan. Undagi elementlarni char turidagi A massivga joylashtirib, tub uzunlikdagi so’zlar sonini aniqlovchi dastur tuzing.

Dastur kodi:
#include
using namespace std;
#define OUT 0
#define in 1
unsigned countwords(char*str)
{
int state = OUT;
unsigned wc = 0;
while(*str)
{
if(*str==' '||*str=='\n'||*str=='\t')
state=OUT;
else
if(state==OUT)
{
state=in;
++wc;
}
++str;
}
return wc;
}
int main(void)
{
char str[]="Bir ikki uch to'rt besh";
cout<<"Tub uzunlikdagi so'zlar soni: " < return 0;
}

Dastur kodi:

#include

using namespace std;
void printAMeans(int A, int B, int N)
{
float d=(float)(B-A)/(N+1);
for (int i=1; i<=N; i++)
cout <<(A+i*d)<<" ";
}
int main()
{
int A=20, B=32, N=5;
printAMeans (A,B,N);
return 0;
