C Number pattern 5 program using For loop:
#include <stdio.h>
int main()
{
int i, j;
for(i=1;i<=5;i++)
{
for(j=1;j<=i;j++)
{
printf("%d",j);
}
printf("\n");
}
return 0;
}
Output:
1
12
123
1234
12345
Explanation:
- The first two integers "i" and "j" are declared of type int.
- Then in the First for loop “i” value is initialized with a value 1.
- Now “i” value is checked with the condition i <= 5 that is (1<= 5). So the condition is True.
- Now the loop enters into the second for loop and checks the condition j <= i.
- So the value of j=1 is equal to the value of "i" it prints the value if "j". Now the value of "j" is incremented to "2" the second for loop condition becomes false loop come out from the for a loop.
- Now the value of "i" is incremented to "2" and repeats the same process.
- Last where “i” value becomes “6” the first for loop condition becomes false and the program terminates.
