C Program to Find Largest Number Using Dynamic Memory Allocation

 

Find the Largest Element in a Dynamically Allocated Memory

#include <stdio.h>
#include <stdlib.h>
int main() {
    int num;
    float *data;
    printf("Enter the total number of elements: ");
    scanf("%d", &num);

    // Allocating memory for num elements
    data = (float *)calloc(num, sizeof(float));
    if (data == NULL) {
        printf("Error!!! memory not allocated.");
        exit(0);
    }

    // Storing numbers entered by the user.
    for (int i = 0; i < num; ++i) {
        printf("Enter Number %d: ", i + 1);
        scanf("%f", data + i);
    }

    // Finding the largest number
    for (int i = 1; i < num; ++i) {
        if (*data < *(data + i))
            *data = *(data + i);
    }
    printf("Largest number = %.2f", *data);

    return 0;
}

Output

Enter the total number of elements: 5
Enter Number 1: 3.4
Enter Number 2: 2.4
Enter Number 3: -5
Enter Number 4: 24.2
Enter Number 5: 6.7
Largest number = 24.20

What is Cloud computing?

Cloud computing refers to the delivery of computing resources and services over the internet, allowing users to access and use applications, storage, and processing power without the need for local infrastructure or hardware. It involves the use of remote servers, typically hosted in data centers, to store, manage, and process data instead of relying on a local computer or server. In cloud computing, users can access a wide range of services and resources on-demand, which are usually provided by a cloud service provider (CSP). These services can include infrastructure resources (such as virtual machines, storage, and networking), platforms for developing and deploying applications, and software applications that can be accessed and used via the internet. Cloud computing offers several advantages over traditional on-premises computing models. It allows for scalability, where users can easily scale up or down their resource usage based on their needs, without having to invest in and mana...

C Program to Read a Line From a File and Display it

  Program to read text from a file # include <stdio.h> # include <stdlib.h> // For exit() function int main () { char c[ 1000 ]; FILE *fptr; if ((fptr = fopen( "program.txt" , "r" )) == NULL ) { printf ( "Error! opening file" ); // Program exits if file pointer returns NULL. exit ( 1 ); } // reads text until newline is encountered fscanf (fptr, "%[^\n]" , c); printf ( "Data from the file:\n%s" , c); fclose(fptr); return 0 ; } If the file is found, the program saves the content of the file to a string  c  until  '\n'  newline is encountered. Suppose the  program.txt  file contains the following text in the current directory. C programming is awesome. I love C programming. How are you doing? The output of the program will be: Data from the file: C programming is awesome. If the file  program.txt  is not found, this program prints an error message.
