C Programming Tutorial - 29 - break

[atsura]

LOL i put max to 1 million and wrote loop
It took 88 seconds

[ZenMasterT]

Thank you much, these tutorials are extremely helpful.
Question: what would I do if I absolutely wanted the user to type a number under 10? Could I include another IF statement under FOR loop specifying that:

if (howmany > 10)
{
printf ("Invalid entry. Please enter a value less than 10.\n");
}

Is this correct?

You are far better than any one BUCKY...
STUPID PROGARAMME 👍👍👍👍

So we can Also use Letters instead of Number
i had Made one and it Works

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

int main()
{
char a;
char howMany;
char maxAmount = 'z';

printf("How many times you wanted this loop to loop? ");
scanf(" %c", &howMany);

for (a='a';a<=maxAmount;a++){
printf("%c\n", a);

if(a==howmany){
break;
}
}

return 0;
}

is it really necassary to have a variable as maxamount=10? cant you just have the for loop be:
for (a=1 ; a=10 ; a++){

[xaveriuskevin]

can i also do this?

int main ()
{

int a;
int z;

printf("your number: ");
scanf("%d", &z);

for (a=1;a<=z;a++)
{
printf("%d", a);
}


return 0;
}

so if i want an error check, maybe like if they put something greater than 10, can i make an if statement saying
if (howmany>10) {printf("please input number between 0 and 1");}

[thestalks]

so you can also do
for(a = 1;a <= howMany ; a++){

printf("Loop: %d", a);
if(a == maxAmount){
break;
}
now im just confusing myself.

bro i wanted to create a program which calculates points from every questio.like the question have options: a, b, c, d and each option have different points, and at the end of the process, it totals out and prints the outcome according to diffrernt points....i am really confused on this....can you give me some tips??

[borntechy]

same program without break
#include <stdio.h>
#include <conio.h>'
#include <ctype.h>
#include <string.h>
#include <math.h>
int main()
{
int times;
int a;
printf("how many times do you want to loop:");
scanf("%d", &times);
for(a=1;a<=times; a++){
printf("%d\n", a);
}

return 0;
}

Why can't I initialize a variable inside of the forloop like > for(int i = 0; i < 5; i++) {} .... It was possible in CS50 ide so I am quite confused atm, does it depend on the ide or what?

[qwerty]

how come you don't need an ampersand right before the a? he did it for howmany, but not a and I don't get why not.

[hence]

Good one but still this doesn't show how many you can loop, its basically loop until the number

[alyskeia]

Why not just write howMany in for instead of maxAmount?

[kzarmair]

what will happen if you use a break in a nested for loop... will it kill both loops or just the first?

[anthonyzhou]

For some reason, my code doesn't work. I'm pretty sure it's correct: 
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
#include <math.h>

int main()
{
    int a;
    int howMany;
    int maxAmount = 10;

    printf("How many rows do you want to print? (up to 10) ");
    scanf(" %d", &howMany);

    for(a=1; a<=howMany; a++){
        printf("%d\n", a);
        if(a==maxAmount){
            break;
        }
    }

    return 0;
}

Why didn't you just set "Maxamount" to whatever the user was entering, then you wouldn't need a break...

[pranjalidwivedi]

can we use **break** inside **IF** statement?

[mehmetsahin]

int a;
int howmany;
int max;

printf("HOW MANY TIMES LOOPS ?\n");
scanf( "%d", &howmany);

printf("What is maximum number ?\n");
scanf( "%d", &max);

for (a = 1; a <= max; a++){
printf( "%d\n", a);

if (a==max){
break;
}
}

[vasiletonofa]

Why don't we just use this way ? : 
int main()
{
  int a, i;
  printf("How many loops?: ");
  scanf("%d", &a);
  for(i=0;i<=a;i++){
    printf("%d", i);
  }
}
