Loop (print some small things)

Print multiples of 7 from 1 to 100
/*
int a=1; Define a Count value
while (a<=100) {//loop detect multiples of 100 or less 7
if (a%7==0) {//7 takes a remainder of zero is a multiple of 7
printf ("%d\n", a);
}
a++; Add 1 to the count after the loop
}
*/
Print numbers from 1 to 100 in single digit 7
/*
int a=1;
while (a<=100) {
if (a%10==7) {
printf ("%d\n", a);
}
a++;

} */
Print numbers from 1 to 100 for 10 bits 7
/*
int a=1;
while (a<=100) {
if ((a-70>=0) && (a-70<=9))
printf ("%d\n", a);
a++;
}*/
Printing 1 to 100 is not a multiple of 7 and does not contain 7 of the number
int a=1;
while (a<=100) {
if ((a%7!=0) && (a%10! = 7)) {
printf ("%d\n", a);



}
a++;
}



Random number
/*
[50,100];
int random=arc4random ()% (100-50+1) +50; Any number to 100 will be less than 100
printf ("%d", random); */
Console input n, use while to print n random numbers (range 10 to 30)
/*
[10,30];
int n=0;
printf ("Please enter a number:");
scanf ("%d", &n); n is the total number of cycles
while (n) {
printf ("%d\n", Arc4random ()% (30-10+1) +10); Print a random number from 10 to 30
n--; 1 reduction per cycle completion
}*/

Break (Terminate Loop), Contine (skip this cycle) two keywords
Do and loop, (at least once)
/*
do{



printf ("Soon after Class");
}while (0); * *
/*
int conut=0;
while (conut<30) {
printf ("%d cycles \ n", conut);
conut++;

}*/

For loop
/*
for (int conut=0;conut<30;conut++) {//First step, the loop variable (conut) executes only once
printf ("%d cycles \ n", conut); Part II, judging the conditions,
Third, if the statement is true, execute the increment, and continue to perform the second step for true return
}*/
Print multiples of 7 from 1 to 100
/*
for (int a=1;a<=100;a++) {
if (a%7==0) {

printf ("%d\n", a);
}
}  */
Print numbers from 1 to 100 in bits 7
/*
for (int conut =1;conut<=100;conut++) {
if (conut%10==7) {
printf ("%d\n", conut);
}
}
