Question

Code is in C

Write a program that reads integers from stdin. Once it reaches the

* end of the input, it prints the smallest absolute value among those

* of the numbers it read.

*

* For example, if

* 4, 6 -3, 3, -2, 13, -4

* are read from stdin, the program should print 2.

*

* If the end of file is reached before any integer is seen, the

* number printed should be INT_MAX (defined in limits.h).

*

* The program should return 0 if successful and -1 if there are

* errors in the input.

*

* You may assume that the absolute value of all negative integers

* successfully read by your program may be stored in an int.

Answer 1

#include <stdio.h>
#include <limits.h>
#include <stdlib.h>
int solve(){

    int num ; // the variable where input is going to be taken upto End Of File
    int smallestAbsValue = INT_MAX; // the variable declared as the smallestAbsVal which will store the smallest Absolute vlaue till the EOF

    int error = 0;

    while(scanf("%d", &num)!=EOF){ // iterating till the EOF (end of file)
    
        if(abs(num) < smallestAbsValue){ // checking the codition for the final Ans
            smallestAbsValue = abs(num); // upadte the answer variable
        }
    }

    printf("Smallest Absolute value is %d ", smallestAbsValue);
    
    return error;
    // if there is an error it should retunr -1
}
int main() {
    
    
    int flag = solve();
    if(flag ==0 ) printf("\nProgramme executed successfully");
    else if(flag == -1) printf("There is Error input");
    return 0;
}
