Question

Give the output of the C program shown below when run with Assume that the file data contains: 5 10 25 45 0 15 Give the output of the C program shown below when run with #include /a.out 213 include #include include /a.out data #include int main( int argc, char *argv int main( int arge, char argv char str[] = "CRIMSON-TIDE" int x = atoi (argv [1]); int y atoi (argv [2]) int z strlen (str) FILE *Epl fopen (argv1], "") int oldVal, num; fscanf ( fp1 , "%d" , #) ; oldVal num; while feof (fpl) for (int a-x a0 ; bab-y) if (numoldVal) printf ("%c", str [a]); printf ("%d ", num-oldVal) ; fscanf (fp1 , "%d" , #) ; printf("%d ", b); printf ("Answer return 0 %d ", o1dVal); . return 0

Explanation / Answer

Explanation of first program is as below:

//Libraries which will be useful in doing operations
//like reading input and printing output
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
using namespace std;

//main function is the entry point for the execution of the program
int main(int argc,char *argv[])
{
//decalred and initialized one character array with the value of "CRIMSON_TIDE"
char str[] = "CRIMSON-TIDE";
//converting the first argument to the integer
int x = atoi(argv[1]);
//converting the second argument to the integer
int y = atoi(argv[2]);
//getting length of the above created array of characters
int z = strlen(str);
//looping over the array of character str and using x as intial point, z as condition and y for the increment
for(int a=x; a<z; a = a+y){
//printing character at the index of a in character array str
printf("%c",str[a]);
}
  
//printing one empty line so that next print statement will start printing in next line
printf(" ");
  
//looping from z and decreasing in value of y till 0
for(int b=z;b>0;b=b-y){
//prinitng the integer
printf("%d ",b);
}
  
//return statement of main function as return type is int
return 0;
}

Explanation of second program is as below:

//Libraries which will be useful in doing operations
//like reading input and printing output
#include <stdio.h>
#include <stdlib.h>
using namespace std;

//main function is the entry point for the execution of the program
int main(int argc,char *argv[])
{
//opening the file whose name is given in arguments 1 and "r" means we are opening the file in read mode
File *fpl = fopen(argv[1],"r");
//declared two integer type of variable but not initialized to any value
int oldVal, num;
//reading integer value from file and storing in num variable
fscanf(fpl,"%d",&num);
//initializing the oldVal as num value
oldVal = num;
//reading the file in loop until we reach the end of the file
while(!feof(fpl)){
//if num is greater then oldVal then this if condition will be true
if(num > oldVal){
//if condition is true then printing the difference between num and oldVal
printf("%d ",num-oldVal);
//assigning the num to the oldVal now
oldVal = num;
}
//reading integer value from file and storing in num variable
fscanf(fpl,"%d",&num);
}
  
//It will print the answer which is basically the largest number in the file
printf("Answer = %d ",oldVal);
  
//return statement of main function as return type is int
return 0;
}
