scanf

#include <stdio.h>

int main(void)
{
    char food[20];
    puts("--------------------------");
    puts(" ** String input/output ** ");
    puts("--------------------------");
    
    printf(" What is your favorite food : ");
    scanf("%s", food);

    What is your favorite food :Hawaiian pizza
    the Food : Hawaiian 
    --------------------------
    scanf cannot use for space 
    --------------------------

}

fgets

• Read String from file

#include <stdio.h>

int main(void)
{
    char food[20];
    puts("--------------------------");
    puts(" ** String input/output ** ");
    puts("--------------------------");
    
    printf(" What is your favorite food : ");
    fgets(food, sizeof(food), stdin);
    
    printf(" the Food : %s", food);
    puts("--------------------------");
    
    return 0;

    /*
    --------------------------
    ** String input/output ** 
    --------------------------
    What is your favorite food : Hawaiian pizza
    the Food : Hawaiian pizza
    --------------------------
    */
}

integer and string input/output

#include <stdio.h>

int main(void)
{
    char sports[10];
    int win;
    
    puts("-------------------------------");
    puts(" ** integer and string ** ");
    puts("-------------------------------");
    
    printf(" What sports : ");
    scanf("%s", sports);
    
    printf(" How many win : ");
    scanf("%d", &win);
    
    printf(" The %s team win %d time(s). \n", sports, win);
    puts("-------------------------------");
    
    return 0;

    /*
    -------------------------------
    ** integer and string ** 
    -------------------------------
    What sports : baseball
    How many win : 10
    The baseball team win 10 time(s). 
    -------------------------------
    */
}

mix input/outpu

#include <stdio.h>

int main(void)
{
    char name[10];
    int year;
    char btype;
    float vision;
    
    puts("-------------------------");
    puts(" ** mix input/output ** ");
    puts("-------------------------");
    
    printf(" Name : ");
    scanf("%s", name);
    
    printf(" Born year : ");
    scanf("%d", &year);
    
    printf(" blood type : ");
    while(getchar() != '\n');
    btype = getchar();
    
    printf(" Vision : ");
    scanf("%f", &vision);
    
    printf("%s's born in %d, blood type : %c and vision : %.1f \n", name, year, btype, vision);
    
    
    return 0;

    /*
