Counting of array elements

Q: nos are entered thru the keyboard and the no. of positive,negative and zero elements also the count of odd and even nos present in the array are displayed

#include

#include

void main()

{

int a[25],i,z=0,p=0,n=0,o=0,e=0;

clrscr();

for(i=0;i<5;i++)

{

printf("enter any no.:");

scanf("%d",&a[i]);

}

for(i=0;i<5;i++)

{

if(a[i]==0)

z++;

else if(a[i]>0)

p++;

else

n++;

}

for(i=0;i<5;i++)

{

if(a[i]%2==0)

e++;

else

o++;

}

printf("no of Zero elements:%d\n",z);

printf("no of positive nos:%d\n",p);

printf("no of negative nos:%d\n",n);

printf("no of odd nos:%d\n",o);

printf("no of even nos:%d\n",e);

getch();

}

Search no. in array

Q: nos are entered thru the keyboard and the no. searched by the user is displayed if it is present in the array

#include

void main()

{

int a[25],i,n,c=0;

clrscr();

for(i=0;i<5;i++)

{

printf("enter any no.:");

scanf("%d",&a[i]);

}

printf("Enter the no. to be searched:");

scanf("%d",&n);

for(i=0;i<=5;i++)

{

if(n==a[i])

c++;

}

if(c>0)

{

printf("%d\n",n);

printf("the no is present %d times",c);

}

else

printf("no. not present in array");

getch();
