Uyga vazifa:

1) Butun toifali pointer orqali int seriyaning maksimal qiymatini toping. (FAQAT POINTER(YA'NI QO'SHIMCHA O'ZGARUVCHISISIZ) VA BITTA SERIYA ISHLARISH KERAK VA SERIYANING ELEMENTLARI O'ZGARMASLIGI KERAK)

Input: A[5]={1,2,3,4,5}
Output: 5

#include #include int main() { int arr[5] = {225,326,-45,85,-92}; int *max = &arr[0]; for (int i = 0; i < 5; i++) { if (*max < arr[i]) { *max = arr[i]; } } printf("%p manzildagi son qiymat %d ga teng\n",&max,*max); return 0; }

2) Haqiqiy son toifali pointer orqali float tipidagi sonning butun qismini chiqaring. (FAQAT POINTER(YA'NI QO'SHIMCHA O'ZGARUVCHISISIZ) VA BITTA O'ZGARUVCHI ISHLARISH KERAK)

Input: son=12.345
Output: 12

int main() { int arr[5]={1,2,3,4,5}; int *sum=&arr[0]; for(int i = 1; i < 5; i++) { *sum +=arr[i]; } printf("sum=%i",*sum ); return 0;

3) Butun toifali pointer orqali int seriya elementlarining yig'indisini toping. (FAQAT POINTER(YA'NI QO'SHIMCHA O'ZGARUVCHISISIZ) VA BITTA SERIYA ISHLARISH KERAK VA SERIYANING ELEMENTLARI O'ZGARMASLIGI KERAK)

Input: A[5]={1,2,3,4,5}
Output: 15

int main() { float arr[5]={1.3,2.2,3.6,4.2,5.5}; float *sum=&arr[0]; for(int i = 1; i < 5; i++) { *sum +=arr[i]; } printf("sum=%f",*sum ); return 0; }

4) Butun toifali pointer orqali int seriyaning birinchi va oxirgi qiymatlarini almashtiring. (FAQAT POINTER(YA'NI QO'SHIMCHA O'ZGARUVCHISISIZ) VA BITTA SERIYA ISHLARISH KERAK)

Input: A[5]={1,2,3,4,5}
Output: A[5]={5,2,3,4,1}

int main(){ int arr[5]={1,2,3,4,5}; for(int i=0; i < 5; i++) { printf("%i,",arr[i]); } printf("\n Almashtirlgan qiymatlar:\n"); int *swap = &arr[0]; arr[1] = *swap; *swap = arr[4]; arr[0] = *swap; arr[4] = arr[1]; for(int i=0; i < 5; i++) { printf("%i,",arr[i]); } return 0; }

5) Butun toifali pointer orqali int seriyaning maksimal va minimal qiymatlarini almashtiring. (FAQAT POINTER(YA'NI QO'SHIMCHA O'ZGARUVCHISISIZ) VA BITTA SERIYA ISHLARISH KERAK)

Input: A[5]={1,2,3,4,5}
Output: A[5]={5,2,3,4,1}
