}Coding works best on desktop or with an external keyboard.
Demonstrates the use of conversion specifiers such as %d, %f, %c, and %s for formatted input and output. Shows how different data types are represented and displayed correctly in C.
#include <stdio.h>
int main() {
int age = 20;
float marks = 89.5;
char grade = 'A';
char name[] = "Alice";
printf("Name: %s\n", name);
printf("Age: %d\n", age);
printf("Marks: %.1f\n", marks);
printf("Grade: %c\n", grade);

}C is a general-purpose, procedural programming language that provides low-level access to memory, efficient performance, and a foundation for system and application software development.
Origin & Creator
Created by Dennis Ritchie at Bell Labs in 1972, originally for developing the UNIX operating system.
Industrial Note
C is essential in embedded systems, OS kernels, compilers, device drivers, and performance-critical applications where low-level memory control and speed are required.
