C Program To Show Square Of Numbers And Find Their Sum #include<stdio.h> int main() { int i=1,n,sq,sum=0; printf("Enter number:\n"); scanf("%d",&n); printf("number\tsquare\n"); while(i<=n) { sq=i*i; printf("%d\t%d\n",i,sq); i++; sum+=sq; } printf("sum is %d",sum); return 0; } OUTPUT

File Handling in C Programming | C Programming Language     C supports a number of functions that have the ability to perform basic file operations, which include:    1. Naming a file    2. Opening a file    3. Reading from a file    4. Writing data into a file    5. Closing a file   

Basic Concept Of Function A function is a block of code that performs a specific task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. Function can also be defined as the idea to put some repeatedly done task together by making block of statement which helps while instead of writing the same block of code again and again for different inputs, we can call the same block of statement in the program.
