Massivlar ustida amallar (amaliy dasturlar)

9 – m i s o l Massiv elementlarini saralash masalasi.

# include # include void main ( ) { float a[ ][3] = {{3,1.2,45},{91,0.3,9},{56,-1,7}}, b; int i, j, k; for ( k = 0; k < 3; k++) for ( i = 0; i < 3; i++) for ( j = 0; j < 2; j++) { if ( a [i] [j] > a [i] [ j +1] ) { b = a [i] [j]; a [i] [j] = a [i] [ j +1]; a [i] [ j+1] = b; } } for ( i = 0; i < 3; i++) { for ( j = 0; j < 3; j++) cout << ” a=” << a [i] [j]; cout << endl; } }

Dastur natijasi:

• 1.2 3 45
• 0.3 9 91
• -1 7 56

Yuqoridagi dastur saralash qator bo’yich olib borish uchun. Agar saralash ustun bo’yich kerak bo’lsa uni quyidagich yozish kerak: for ( i = 0; i < 2; i++) for ( j = 0; j < 3; j++) { if ( a [i] [j] > a[i+1][ j] ) { b = a[i] [j]; a [i] [ j] = a[i+1][ j]; a [i+1] [ j] = b; }

A matrisasini quyidagicha tashkil etish kerak: arctg(i+j) + 4,642*j ; agar i+j<4 Ai j = d+3*| i-j | + j2 __________________ ; agar i+j>=4 ( i = j = 6 ) | i-j|2 + 0,935*j 1-qator elementlarining yig’indisini toping va matrisaning 3-qatoridagi elementlarini shu songa ko’paytirib vector hosil qiling. Natijalarni massiv shaklida chiqaring. d - ixtiyoriy son
