C Language and programming routines-C language program first experience

Let the program calculate: Sum of two numbers of A and b

#include <stdio.h>int main () {int a,b,sum;    scanf ("%d%d", &a, &b);    Sum=a+b;    printf ("%d\n", sum); return 0;}

User interface-friendly (or gibbering) program

#include <stdio.h>int main () {int a,b,sum;    printf ("Please enter two integers:");    scanf ("%d%d", &a, &b);    Sum=a+b;    printf ("The sum of these two integers is:%d\n", sum); printf ("The calculation is complete, thank you for using!"    \ n "); return 0;}

Re-example: feet to meters conversion

#include <stdio.h>int main () {float f,m;    printf ("Enter the length in Feet:");    scanf ("%f", &f);    m = f/3.28;    printf ("%f feet is%f meters.\n", F, M); return 0;}
