Matrisalar bilan ishlashga doir turli dasturlar

1-masala. 3ta qator va 4ta ustunga ega A matrisa berilgan. Shu matrisaning eng kichik elementini va uning indeksini topish, hamda shu element turgan qatorni massiv shaklida chiqarish dasturini tuzing.

# include # include void main ( ) { float a[3][4] = {{1.1, -2,0.3,4},{44,5.3,6.9,71},{7,8.8,9,1}}, i, j, k, h, min, b[4]; min = a[0][0]; for (i=0; i<3; i++) for (j=0; j<4; j++) { if ( a[ i ][ j ] < min) { min = a[ i ][ j ]; k = i; h = j; } } cout << “min=”<

2-masala. Matrisani transponirlash uchun dastur tuzing. Transponirlash deb ustun va satr elementlarining o’zaro o’rin almashishiga aytiladi, ya’ni

# include # include void main ( ) { int a[3][3] = {{1,2,3},{4,5,6},{7,8,9}}, b[3][3], i, j; for ( i=0; i<3; i++) { for ( j=0; j<3; j++) { b[ i ][ j ] = a[ j ][ i ]; cout <<”b[“<

3-masala. Matrisaning izini hisoblash dasturini tuzing. Matrisaning izi deb bosh diagonal elementlarinig yig’indisiga aytiladi.

(Xatosini toping!) # include //# include void main ( ) { int a[3][3] = {{3,4.5,6},{0.4,8,5.9},{9.2,6.5,88}}, s1=0; int i, j, k; for ( i=0; i <= 3; j++) s1 = s1 + a[ i ][ j ]; cout << ”s1=”<< s1 << end; getch ( ); return 0; }

1-variant: # include # include void main ( ) { float a[3][3] = {{3,4.5,6},{0.4,8,5.9},{9.2,6.5,88}}, s1=0; int i ; for ( i=0; i < 3; i++) s1 = s1 + a[ i ][ i ]; cout <<”s1=”<

2-variant: # include # include void main ( ) { float a[3][3] = {{3,4.5,6},{0.4,8,5.9},{9.2,6.5,88}}, s1=0; int i, j ; for ( i=0; i < 3; i++) for ( j=0; j < 3; j++) if ( i = = j) s1 = s1 + a[ i ][ j ]; cout <<”s1=”<

4-masala. 2 ta matrisa berilgan. Ularni o’zaro ko’paytirib yangi matrisa hosil qilish dasturini tuzing. Izoh: 1-matrisaning ustunlar soni 2-matrisaning satrlar soniga teng bo’lishi kerak.
