How to run c program on linux(ubuntu) terminal with fixing problems

 We can easily code c using linux terminal commandline bellow showing tips

At first we have to enter desktop file so use command

$cd Desktop

$touch helloworld.c

next enter the file helloworld.c and code inside the file and save 

that code:

#include <stdio.h>

int main() {

    printf("i am ibnsina himel!\\n");

    return 0;

}

Now we have to put c running command

gcc helloworld.c -o helloworld

./helloworld

Next we can see that the c file starts executing

on other case if you find problem in executing that code in terms gcc related problems like bellow

to fix this problem we have to do some changes

sudo apt update

sudo apt install gcc -y

gcc --version

gcc helloworld.c -o helloworld

./helloworld

Another example of calculator app using c in linux terminal

tab exit you will get saving option

now put the executing command as before,mission successful

 code that used to make simple calculator:

#include <stdio.h> int main() { double num1, num2, result; char operator; // Taking user input printf("Enter first number: "); scanf("%lf", &num1); printf("Enter an operator (+, -, *, /): "); scanf(" %c", &operator); printf("Enter second number: "); scanf("%lf", &num2); // Performing operation switch (operator) { case '+': result = num1 + num2; printf("Result: %.2lf\n", result); break; case '-': result = num1 - num2; printf("Result: %.2lf\n", result); break; case '*': result = num1 * num2; printf("Result: %.2lf\n", result); break; case '/': if (num2 != 0) result = num1 / num2; else { printf("Error: Division by zero is not allowed.\n"); return 1; } printf("Result: %.2lf\n", result); break; default: printf("Error: Invalid operator.\n"); } return 0; }

Thus you can do c program on linux terminal without any c compiler as codeblocks
