8-Mavzu. Bir o‘lchovli va ikki o`lchovli massivlar ustida amallar bajarishga doir dasturlar tuzish

Misollar
1. ni hisoblash dasturini tuzing.


Dasturi:
#include
#include
using namespace std;
int main ()
{
float a[3][5], S,P; int i,j;
cout<<"Massiv elementini kiriting:"< for (i=0; i<3; i++)
for (j=1; j<5; j++)
cin>>a[i][j];
S=0;
for (i=0; i<3; i++)
{
P=1;
for (j=1; j<5; j++)
P=P*pow(a[i][j],0.5);
S=S+P;
}
cout<<"S="< return 0;
}

Ikki o‘lchovli dinamik massivlar. Ikki o‘lchovli dinamik massiv umumiy ko‘rinishda quyidagicha ikki bosqichda e’lon qilinadi:
t **b;
bu yerda:
b – massiv nomi;
t – massiv elementlari turi.
Masalan, float **matr;
Bunda haqiqiy sonlardan tashkil topgan matr nomli ikki o‘lchovli massiv e’lon qilinmoqda.
Massiv uzunligi new protsedurasi yordamida ikki bosqichda aniqlanishi lozim.
Masalan,
matr=new float *[m];
for (i=0; i

2. m x n o‘lchamli ikki o‘lchovli massivning 3-ustunini k soniga ko‘paytiring va o‘zgartirilgan massivni ekranga chiqarish dasturini tuzing.

Dasturi:
#include
#include
using namespace std;
int main ()
{
int i,j,m,n,k;
float **a;
cout<<"Qatorlar soni m="; cin>>m;
cout<<"Ustunlar soni n="; cin>>n;
a=new float *[m];
for (i=0; i cout<<"Massiv elementlarini kiriting:"< for (i=0; i for (j=0; j>a[i][j];
cout<<"ko'paytiriadigan son k="; cin>>k;
for (i=0; i for (i=0; i {
for (j=0; j cout<<" a["< cout< }
return 0;
}

3. Ikki o‘lchovli a va b massivlar yig‘indisini topish dasturi tuzilsin.

#include

#include
using namespace std;
int main ()
{
int i,j,m,n;
float **a,**b,**c;
cout<<"Qatorlar soni m="; cin>>m;
cout<<"Ustunlar soni n="; cin>>n;
a=new float *[m];
for (i=0; i b=new float *[m];
for (i=0; i c=new float *[m];
for (i=0; i cout<<"a massiv elementlarini kiriting:"< for (i=0; i for (j=0; j>a[i][j];
cout<<"b massiv elementlarini kiriting:"< for (i=0; i for (j=0; j>b[i][j];
cout<<"a va b massivlar yig'indisi c massiv quyidagicha:"< for (i=0; i {
for (j=0; j cout<<" c["< cout< }
return 0;
}
