Single Integer

Another array example

//Find the lowest number in the array num[10]

main()

{

int num[10]={4,9,11,2,13,77,8,19,21,1};

int min, i;

min = num[0];

for (i=1; i<10; i++) {

  if (num[i] < min)

     min = num[i];

}

printf(“The minimum is %d”, min);

}

—Array example

—

/* which type of integer is valid in array declaration*/

#include <stdio.h>

int main(void)

  {

  int x[5];  /* x[5] is array initialization /

  x[0]=23;  /* valid */

  x[2.3]=5;  /* invalid: index is not an int */

  return 0;

  }

Examples

int x [5] = { 1,2,3,4,5 };  size 10 bytes

—creates array with elements 0-4 values 1-5

int x [5] = {4,3};  size 10 bytes

—creates array with elements 0-4 values 4,3,0,0,0

int x [ ] = {1,2,3};  size 6 bytes

—creates array with elements 0-2 values 1,2,3

char c[4] = {‘M’, ‘o’ , ‘o’ };  size 4 bytes

—creates array with elements 0-3 values M o o NULL
