August 15, 2016 Published by: Sajjad Baghaee

Note:

//Define array:
char name[15]= “Sajjad Baghaee”;
// replacing a character in an array :
name[2]= ‘C’;
Array start by 0 so S=0 a=1 j=2 j=3 a =4 d=5 =6 B=7 a=8 g=9 h=10 a=11 e=12 e=13

Code:
—————————

#include <stdio.h>
#include <stdlib.h>

int main()
{

char name[15]= “Sajjad Baghaee”;
printf(“This is %s \n”, name);
name[2]= ‘C’; // replacing the 1st character “j” in array “Sajjad Baghaee” with “C”
name[3]=’c’; // replacing the 2nd character “j” in array “Sajjad Baghaee” with “c”
printf(“This is %s\n”,name);

return 0;

C Programming Tutorial – 3 – what can we do with “printf()” ? :

August 15, 2016 Published by: Sajjad Baghaee

Code:
—————————

#include <stdio.h>
#include <stdlib.h>

int main()
{

// Print “Hello world!” on the screen + goes to new line
printf(“Hello world!\n”);

// Print “Hi Sajjad” on the screen + insert a tab space
printf(“Hi Sajjad\t”);

// Print “This is a tab test” on the screen + goes to new line + make a alarm sound
printf(“This is a tab test\n\a”);

// Conversion string use %s to replace a string
printf(“%s is an intelligent boy and %s\n” , “SAJJAD”,”programmer”);

// Conversion integer use %d to replace a integer number
printf(“I ate %d eggs last morning\n”,2);

// Conversion decimal use %f to replace a decimal number
printf(“my weight is %f\n”, 80.467896212);

// Conversion decimal use %.4f to replace a decimal number with 4 decimal number
printf(“my weight is %.4f\n”, 80.467896212);

// Conversion decimal use %.2f to replace a decimal number with 2 decimal number
printf(“my weight is %.2f\n”, 80.467896212);

return 0;
