5) What will be the output of following program ? #include <stdio.h> int main() { static int array[]={10,20,30,40,50};printf("%d...%d",*array,*(array+3)* *array);return 0; }

Error

10...40

10...300

10....400

Answer Correct Answer - 4
10...400
In expression printf("%d...%d",*array,*(array+3)* *array);, *array is 10, *(array+3) is 40. 5)以下程序的輸出是什么？

錯誤

10 ... 40

10 ... 300

10 .... 400

回答 正確答案-4
10 ... 400
在表達式中printf(“％d ...％d”，* array，*(array + 3)* * array); ，* array是10 ，*(array + 3)是40 。 6) What will be the output of following program ? #include <stdio.h> int main() { int a[5]={1,2,3,4,5},b[5]={10,20,30,40,50},tally;for(tally=0;tally< 5;++tally)*(a+tally)=*(tally+a)+ *(b+tally);for(tally=0;tally< 5;tally++)printf("%d ",*(a+tally));return 0; }

This is a simple program to add elements of two arrays, you can access array elements using *(tally+a) Or *(b+tally) Or a[tally] . 6)以下程序的輸出是什么？

1 2 3 4 5

10 20 30 40 50

11 22 33 44 55

這是一個添加兩個數組元素的簡單程序，您可以使用*(tally + a)或*(b + tally)或a [tally]訪問數組元素。 .minHeight{min-height: 250px;}@media (min-width: 1025px){.minHeight{min-height: 90px;}} .minHeight{min-height: 250px;}@media (min-width: 1025px){.minHeight{min-height: 90px;}} 7) What will be the output of following program ? #include <stdio.h> int main() { int a[5]={0x00,0x01,0x02,0x03,0x04},i;i=4;while(a[i]){printf("%02d ",*a+i);--i;}return 0; }

00 01 02 03 04

04 03 02 01 00

04 03 02 01

01 02 03 04

Answer Correct Answer - 3
04 03 02 01
0x00,0x01,0x02,0x03,0x04,0x05 are hex values of 0,1,2,3,4,5.
while(a[i]) will be terminated by a[0], becuase value of a[0] is 0 hence, 04,03,03,01 will print. 7)以下程序的輸出是什么？

00 01 02 03 04

04 03 02 01 00

04 03 02 01

01 02 03 04

回答 正確答案-3
04 03 02 01
0x00,0x01,0x02,0x03,0x04,0x05是十六進制值0、1、2、3、4、5。
while(a [i])將以a [0]終止，因為a [0]的值為0，因此將打印04、03、03、01。 8) What will be the output of following program ? #include <stdio.h> int main() {char X[10]={'A'},i;for(i=0; i<10; i++)printf("%d ",X[i]);return 0; }

A 0 0 0 0 0 0 0 0 0

A

A 32 32 32 32 32 32 32 32 32

ERROR

Answer Correct Answer - 1
A 0 0 0 0 0 0 0 0 0
char X[10]={'A'}; 0^th index of X is assigned by 'A' and rest of elements is assigned by 0. 8)以下程序的輸出是什么？

A 0 0 0 0 0 0 0 0 0

一個

A 32 32 32 32 32 32 32 32 32

錯誤

回答 正確答案-1
A 0 0 0 0 0 0 0 0 0
字符X [10] = {'A'}; X的^第 0 ^個索引由“ A”分配，其余元素由0分配。 9) Which is an incorrect declaration of one dimensional array ?

int x[5];

int x[5]={1,2,3,4,5};

int x[5]={1,2};

int x[];

Answer Correct Answer - 4

int x[];
You can ignore value within the subscript [] when you are initialising array with elements, but here no initialisation found.

9)哪個是一維數組的不正確聲明？

int x [5];

int x [5] = {1,2,3,4,5};

int x [5] = {1,2};

int x [];

回答 正確答案-4

int x [];
當您使用元素初始化數組時，可以忽略下標[]中的值，但是在此找不到初始化。
