Re type the code and fix any errors. The code should convert negative numbers to 0.

if (userNum >= 0)
   printf("Non-negative\n");
else
   printf("Negative; converting to 0\n");
   userNum = 0;
 
printf("Final: %d\n", userNum);

solution

#include <stdio.h>

int main(void) {
 int userNum = 0;


 if (userNum >= 0){
 printf("Non-negative\n");
}
else{
 printf("Negative; converting to 0\n");
 userNum = 0;
 }
 printf("Final: %d\n", userNum);

return 0;
}

Multiple branch If-else statement: Print century.

Write an if-else statement with multiple branches. If givenYear is 2100 or greater, print “Distant future” (without quotes). Else, if givenYear is 2000 or greater (2000-2099), print “21st century”. Else, if givenYear is 1900 or greater (1900-1999), print “20th century”. Else (1899 or earlier), print “Long ago”. Do NOT end with newline.

#include <stdio.h>

int main(void) {
 int givenYear = 0;

givenYear = 1776;

if(givenYear >= 2100){printf("Distant future"); } 
else if(givenYear >= 2000){printf("21st century"); } 
else if(givenYear >= 1900){printf("20th century"); }
else {printf("Long ago"); }

return 0;
}

Multiple if statements: Print car info.

Probably has seat belts.
Probably has anti-lock brakes.

#include <stdio.h>

int main(void) {
 int carYear = 0;

carYear = 1940;

if(carYear <= 1969){printf("Probably has few safety features.\n"); } 
if(carYear >= 1970){printf("Probably has seat belts.\n"); } 
if(carYear >= 1990){printf("Probably has anti-lock brakes.\n"); }
if(carYear >= 2000){printf("Probably has air bags.\n"); }

return 0;
}
