Program: 103
Write a c program to print all prime numbers from 1 to 300. (Hint: Use Nested loops, break and continue)
#include<stdio.h> #include<conio.h> int main() { int num, max=300, i, flag; //create a for loop to run a counter from 1 to 300. for(num=1;num<=max;num++) { flag=0; //second for loop to check the number from 1 to 300 is prime or not. for(i=2;i<=num/2;i++) { if(num%i==0) { flag=1; break; } } if(flag==0 & num!=1) // we remove 1 from this condition printf("%d\t", num); } }
Output:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293
