C array elements

C Program to Read Array Elements

#include

#include

int main()

{

int i,arr[50],num;

printf("\n Enter no of elements: ");

scanf("%d"&,num);

printf("\n Enter the values: ");

for(i=0;i

{

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

}

for(i=0;I,num;i++)

{

printf("\n Arr[%d]=%d",i,arr[i]);

}

return(0);

}

C Program to Search an element in Array

#include

#include

int main()

{

int a[3],ele,num,i;

printf("\n Enter no of elements: ");

scanf("%d",&num);

printf("\n Enter the values: ");

for(i=0;i

{

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

}

printf("\n Enter the elements to be searched : ");

scanf("%d",&ele);

i=0;

while(i

{

i++;

}

if(i

{

printf("Number found at the location = %d",i+1);

}

else

{

printf(“Number not found");

}

return (0);

}

Output

Enter no of elements : 5

11      22      33      44      55

Enter the elements to be searched : 44

Number found at the location =4

Print the Program Name and All its Arguments

#include

#include

           void main(int argc, char *argv[])   

{

int i;

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

{

   printf("%s ", argv[i]);       

}

printf("\n");

}

Compute First N Fibonacci Numbers using Command Line Arguments

#include 

#include

int first = 0;

int second = 1;

int third;

void rec_fibonacci(int);

void main(int argc, char *argv[])

{

int number = atoi(argv[1]);

printf("%d\t%d", first, second); 

rec_fibonacci(number);

printf("\n");

}

void rec_fibonacci(int num)

{

           if (num == 2)    

{

return;

}

third = first + second;

printf("\t%d", third);

first = second;

second = third;

num--;

rec_fibonacci(num);

}

Output

 0       1       1       2       3       5       8       13      21      34

Generate Fibonacci Series of N Numbers using Command-Line Argument

#include 

#include   

void main(int argc, char * argv[])

{

int n, last = 0, prev = 1, curr, cnt;

n = atoi(argv[1]);

printf("Printing first %d fibonacci nos. -> ", n);

printf("%d ", last);

printf("%d ", prev);

cnt = 2;

while (cnt< = n-1)

{

curr = last + prev;

last = prev;

prev = curr;

cnt++;

printf("%d ", curr);

}

printf("\n");

}

Output

Printing first 10 fibonacci nos. -> 0 1 1 2 3 5 8 13 21 34

Input 3 Arguments and Operate Appropriately on the Numbers

#include 

#include  

void main(int argc, char * argv[])

{

int a, b, result;

char ch;

printf("arguments entered: \n");

a = atoi(argv[1]);

b = atoi(argv[2]);

ch  = *argv[3];

printf("%d %d %c", a, b, ch);

switch (ch)

{

case '+':

result = a + b;

break;

case '-':

result = a - b;

break;

case 'x':

result = a * b;

break;

case '/':

result = a / b;

break;

default:

printf("Enter a valid choice");

}

printf("\nThe result of the operation is %d", result);

printf("\n");    

}

Output

5 4 +

arguments entered:

5 4 +

The result of the operation is 9
