* C program to Convert Decimal to Octal
long decimalnum, remainder, quotient;
int octalNumber, i = 1, j;
printf("Enter the decimal number: ");
quotient = decimalnum;
while (quotient != 0)
octalNumber[i++] = quotient % 8;
quotient = quotient / 8;
printf("Equivalent octal value of decimal no %d: ", decimalnum);
for (j = i - 1; j > 0; j--)
Output: $ cc pgm11.c $ a.out Enter the decimal number: 68 Equivalent octal value of decimal no 68: 104
